  • Digital image subtraction of temporally sequential chest images by rib image elimination

    We studied image subtraction of temporally sequential chest images by rib image elimination. The image subtraction presents clinically useful information related to interval changes in chest images. Clinical chest images are not usually reproducible in terms of patient positioning, X-ray projection, inspiration, cardiac pulsation, etc. A proper image registration is needed prior to the subtraction. An image registration method by nonlinear warping was suggested [A. Kano et al., 1994]. In the method, template regions of interest and the corresponding search area regions of interest are selected in the lung areas on the two images. The method provides an improper image registration for some pairs of temporally sequential images. One of the reasons for the improper image registration is the difference between the shifts of lung and rib by inspiration. Some pairs of temporally sequential chest images show large difference of lung position in the pairs in spite of small difference of rib position in the pairs. In this case, the method does not provide a proper image registration. To get the proper image registration of the temporally sequential images with different position changes for the rib and lung, we eliminated rib images from the chest images assuming that the contribution of rib to the chest image is uniform. The nonlinear warping was then applied to the rib eliminating images leading to the properly registered images and enhanced interval changes.

  • Detection and Classification of Moving Object for Smart Vision Sensor

    Conventional surveillance system requires human power to monitor and thus not applicable for a long hour monitoring. An automated method is proposed here, an integration of a moving object detection and recognition. First, the moving object is detected and segmented by using selectiveness adaptive background subtraction technique followed by noise and shadow removal algorithm for removing disturbances. Then, standardize moment invariant is employed to extract the features for each moving blobs. To recognize these blobs, the calculated moment values are fed to a neural network module that is equipped with trained extracted moment values for human and vehicle silhouettes. The results of the experiments showed a satisfied performance with the proposed approach

  • A novel spectral subtraction technique for cognitive radios

    In the past a lot of work has been done to remove noise from speech. Most of the presented techniques were derived from Boll's spectral subtraction technique. Roughly speaking the spectral subtraction techniques consists of estimating the noise power during the periods when no speech is present and subtracting this estimate of the noise power from the signal when speech is present. This spectral subtraction technique could be a very good in-band de- noising technique for communication signals measured by cognitive radios. However, there is one major drawback: one can never turn off the spectrum so that no communication signals are present. This paper presents an extended version of the spectral subtraction technique which does not require `speech free' periods, but can determine the noise power from the empty frequency bins in the spectrum. The presented method is based on an autoregressive (AR) model, which is linear in the parameters. Simulation results show that the presented technique is as performing as the original spectral subtraction techniques without the need to turn off the signals.

  • Temporal subtraction method for abdominal contrast and non-contrast image based on image matching techniques

    Recently, the death rate due to the liver cancer rises remarkably. To reduce the rate, the early detection of the disease is important. To detect diseases in early stage which are concern cancer, image diagnosis such as CT image is used in medical fields. On the other hand, the burden to a radiologist becomes increase. Therefore, the development of a system reducing the burden of the radiologist is important. In order to diagnose abnormalities based on medical imaging there are some reports. But, there is no report which is concern with detecting abnormality on liver disease based on temporal subtraction technique for abdominal CT image. As one of the methods to analyze abnormalities on visual screening, temporal subtraction technique is useful. This technique subtracts past image to current one. To obtain the good performance based temporal subtraction technique, image registration is most important task. In this paper, we propose a registration method for liver CT image using voxel matching techniques. We describe our registration method from two CT image which obtained deference time series and shows experimental results with discussion.

  • Improving Bit Error Rate of OCDMA Systems Using AND Subtraction Technique

    A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing double-weight (DW) code against the existing code, Hadamard. In this paper we have proved that AND subtraction technique gives better bit error rates (BER) performance than complementary subtraction technique against the received power level. The overall system cost and complexity can be reduced by using less number of filters in this technique. At the same time, the performance of the OCDMA system is improved significantly because with less number of filters in the decoder, the total power loss can be reduced and this can be clearly seen in the result

  • Simple and Efficient Numerical Evaluation of Near-Hypersingular Integrals

    Simple and efficient numerical procedures for evaluating the gradient of Helmholtz-type potentials are presented. The convergence behavior of both normal and tangential components of the gradient is examined. It is also shown that the scheme for handling near-hypersingular integrals is effective for handling nearly singular potential integrals as well, so the same quadrature scheme may be used for both simultaneously.

  • On the double potential integrals arising in the method of moments and their analytic-numeric hybrid treatment

    A very simple alternative analytical approach to calculate the free space static potential integral associated to uniform source distributions over arbitrary oriented flat polygons is presented. The technique is based on a novel integral transformation and the resulting formula is equivalent to others existing in literature, being also suitable within a singularity subtraction framework. The numerical integration of the obtained analytical expression is performed by utilizing Generalized Cartesian product rules built on the double exponential formula. Therefore, the problems linked to the endpoint singularities in the derivative of the potential are eased. These techniques are used within a surface integral equation-Method of Moments framework.

  • Foreground model for background subtraction with blind updating

    Background subtraction is a key pre-processing step for several video automatic operations. Various techniques have been proposed to perform background subtraction automatically in complex environments. Visual background extractor (ViBe) is a popular background subtraction technique that can initialize its model in a single frame, adapt to the environment changes and achieve satisfactory subtraction results. In this paper, we propose to use ViBe with blind updating which can more quickly adapt to dynamic environment changes. We propose foreground model with adaptive updating strategy to assist the ViBe with blind updating to detect slow moving object without introducing the ghost phenomenon. Experimental results have verified the performance of the proposed technique.

  • A comparison of scatter compensation methods in SPECT: subtraction-based techniques versus iterative reconstruction with accurate modeling of the scatter response

    The authors compare two subtraction-based techniques, dual window and convolution subtraction, to iterative reconstruction incorporating an accurate model of the scatter response. Two phantoms, consisting of a cylindrical attenuator with circular cross section and hot or cold rods, were used. Projection data were simulated using Monte Carlo techniques. They were reconstructed using the maximum-likelihood-expectation maximization (ML-EM) algorithm with a projector/backprojector that accurately models photon attenuation and the spatially variant geometric and scatter responses. In addition, the data were scatter-compensated using the subtraction techniques and then reconstructed using ML-EM with a projector/backprojector modeling only attenuation and collimator response. It was found that the images reconstructed with the accurate scatter model are superior in terms of mean square error, standard deviation, and signal-to-noise ratio to data reconstructed following scatter subtraction. The quantitative accuracy of the images reconstructed with subtraction techniques depends critically on the selection of subtraction parameters.<<ETX>>

  • A No-reference video quality assessment based on two-pass edge analysis and background subtraction

    A novel no-reference video quality assessment is proposed in this paper. The proposed metric is based on the combination of two-pass edge analysis and background subtraction. The two-pass edge analysis is a blur metric we proposed in our previous work, which has gain an efficient performance in image blur assessment and other image processing applications. We apply the two-pass edge analysis to the video quality assessment in order to calculate the quality of each frame in the video. On the other hand, considering that one will pay his most attention on the foreground of the video. So we also apply the background subtraction to get the foreground of the video and only use these foreground to calculate the video quality. Experiments in the last section shows that our proposed no-reference metric has a good performance in the test sequences.
