  • Design and Implementation of Low-Cost LK Optical Flow Computation for Images of Single and Multiple Levels

    Lucas-Kanade (LK) optical flow algorithm is widely used for moving object detection and tracking by computing the motion vectors of pixels in image sequences. Due to the high computation complexity, optical flow computation is one of the crucial operations in many computer vision applications. This paper presents a low-cost hardware implementation of the LK optical flow algorithm. In particular, we design a low-cost divider used in the matrix inversion, leading to significant reduction in delay and area for calculation of small optical flow vectors. Furthermore, we also design a pyramidal LK optical flow computation unit that can process images of different sizes in order to increase the magnitude range of optical flow vectors.

  • Motion Analysis and Research of Local Navigation System for Visual-Impaired Person Based on Improved LK Optical Flow

    For the problem of low detection accuracy and slow speed to fast motion object, when solving the basic optical flow constraint equation with the traditional algorithm, an improved optical flow algorithm based on LK optical flow algorithm has been put forward in this paper. The intensive optical flow is the biggest characteristic of the algorithm, the structure of the sampling pyramid executive optical flow, the second from bottom to date, and the second from bottom optical flow numerical multiply 2, through the double linear interpolation get the bottom of the optical flow. In the final layer iterative initialization, set specific optical flow threshold value, before a layer of iterative result for less than the response of the threshold value point, known as moving range too small point, it directly set the optical flow number to zeros and skip this point, reduce the computation time. The results shows that this improved optical flow algorithm, which can accurately analysis and forecast in the scene or particular movement of the target of the campaign mode, has the advantages of not only a high precision of motion estimation and a strong anti-interference, but also a better speed compared with the tradition optical flow algorithm.

    Optical flow algorithm is an important approach to estimate motion from image sequence. Using it can effectively analyze the dynamic information of facial expressions and extract the characteristic flow which can reflect the facial expression changes. In this paper, based on the Lucas-Kanade optical flow algorithm, the Hession matrix is introduced to filter the unreliable constraint points in the local neighborhood and improve the accuracy of the optical flow field in facial expression changes. Experimental results show the proposed method offers a better performance for the Lucas-Kanade optical flow algorithm.

  • Matlab programmed method for the optical flow estimation based on the integral image

    The Optical Flow computation is the estimation of the apparent displacement of the object on an image sequence (actual image and next image). There are different methods for Optical Flow estimation, standing out exhaustive methods and differential methods. Differential Methods propose a model that considers the error in the Optical flow estimation. This model is minimized solving the Euler-Lagrange equations of linearized versions of the functional terms like in the differential model developed by Horn & Schunck. The exhaustive methods take a point and his environment in the actual image and search for the more similar in the next image like in the Steinbücker model of Exhaustive Search. In this paper is presented the implementation of the differential methods of Horn & Schunck and the Steinbücker's exhaustive “variational” method. Additionally it is posed a new method that combines the differential method and the exhaustive one. With the use of the integral image and a cost volume it manages to obtain a processing time reduction of the exhaustive methods close to a 98% in comparison to a similar implementation in Matlab. Through the implementation of the combined methods it is possible to reach below 15 degrees in average angular error (AAE).

  • The Compensated HS Optical Flow Estimation Based on Matching Harris Corner Points

    In this paper we develop a novel approach called the compensated HS (CHS) optical flow estimation algorithm to improve the precision of the large displacement optical flow field. For the lack of the higher order term in the optical flow constraint equation, the traditional optical flow estimation based on the first-order gradient always produce the optical flow field with obvious error in the case of large image displacement. We compensate the optical flow constraint equation with the fitted higher-order term through matching the corner points extracted by the Harris detector. And then, we use it to construct the new energy function and derive the new Gauss-Seidel iterative solution of the optical flow. To the existence of multi-motion pattern, we adopt k-means algorithm to cluster these pattern and point-by- point fit the higher order terms of different pattern. The final experiments show that this algorithm could obviously improve the precision of the large displacement optical flow and of the optical flow in the smooth region.

  • Registration of multimodal brain images based on optical flow

    An improved registration method of multimodal brain images combined optical flow and Speeded-Up Robust Features (SURF) is presented in this paper. Firstly, histogram specification is used to transform modal of images before registration, the similar modal of images are beneficial to the following image registration. Secondly, the feature points are extracted by SURF, and then the preliminary registered image could be obtained. Thirdly, with the obtained registered image, optical flow algorithm is used to achieve the accurate results. Finally, several typical multimodal brain images are employed to evaluate the performances of the proposed approach, Demons based method, SURF based method and Mutual Information (MI) based method. Experimental results show that the measure indexes of Mean Squared Error (MSE), Peak Signal to Noise Ratio (PSNR) and correlation coefficient (Rcc) of our method are more competitive compared with the other methods, which indicate the proposed approach has the higher accuracy and better robustness.

  • Noise Resistance Global Method Optical Flow Using Adaptive Lorentzian Influence

    This paper presents the using of adaptive Lorentzian influence with the global method optical flow for noise resistance on the visual progression. In particular, optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. It is 2D vector field where each vector is a displacement vector showing the movement of points from the first frame to second. When the image flow is degraded by noise, the performance for approximating the vector in optical flow is incorrect. With adaptive Lorentzian influence, we ensure more desirable noise resistance in global method optical flow in our experiment. We also test the using of adaptive Lorentzian influence over many noise resistance models when they proceed on global method optical flow. Many intensities of the additive white Gaussian (AWG) noise from low to high intensity of noise are utilized in our experiment to ensure our proposed method.

The main task in violence detection is to detect moving objects and classify their behavior using mean of intensity as violent or non-violent.

  • Moving Target Detection and Tracking Based on Pyramid Lucas-Kanade Optical Flow

    In order to enable the optical flow to track larger and faster moving targets, pyramid Lucas-Kanade optical flow method is used to detect and track moving targets. First, detecting the corners which is easy to track, in order to improve the tracking accuracy, detected corners and then calculate the sub- pixel corner, and then the video in each frame of the image layered in the image pyramid to calculate the optical flow at the top corner, use the next pyramid as the starting point of the pyramid and repeat this process until the bottom pyramid image, which can overcome the Lucas-Kanade optical flow method cannot track faster and larger movements the shortcomings, to achieve the tracking of moving goals.

  • Moving vehicle detection based on optical flow estimation of edge

    This paper proposed a moving vehicle detection algorithm based on optical flow estimation on an edge image. Using the Canny operator, the image edge is obtained and refined. Then a set of feature points is extracted from the edge image. The pyramid model of Lucas-Kanade optical flow is used to calculate the optical flow information of the feature point set. A new algorithm, which is called the weighted Kmeans optical flow clustering algorithm, is proposed to cluster feature points and used to identify vehicle pattern of the feature point set on the optical flow so that the moving vehicle can be efficiently extracted from the complicated dynamic background. In this paper the vehicle videos, which are captured by a camera on a moving car, are used as the test data set. The experimental results show that this algorithm can effectively detect the moving vehicles in the videos from the camera on the moving car.
