Optimal Filter Estimation for Lucas-Kanade Optical Flow
Optical flow algorithms offer a way to estimate motion from a sequence of images. The computation of optical flow plays a key-role in several computer vision applications, including motion detection and segmentation, frame interpolation, three-dimensional scene reconstruction, robot navigation and video compression. In the case of gradient based optical flow implementation, the pre-filtering st...
متن کاملOptical Flow Measurement using Lucas Kanade Method
Motion estimation is demanding field among researchers to compute independent estimation of motion at each pixel in most of general. Motion estimation generally known as optical or optic flow. In this paper, overview of some basic concepts of motion estimation, optical flow and Lucas kanade method has been provided by us. Lucas kanade method is one of the methods for optical flow measurement. I...
متن کاملEstimation of Vehicle’s Lateral Position via the Lucas-Kanade Optical Flow Method
The use of rumble strips on roads has proven to be an effective means of providing drivers lane departure warning (LDW). However, rumble strips require an infrastructure and do not exist on a majority of roadways. Therefore, it is desired to develop an effective virtual rumble-strip LDW system. However, before developing such a system, it is essential that we know the vehicle’s lateral characte...
متن کاملExtended Lucas-Kanade Tracking
The Lucas-Kanade (LK) method is a classic tracking algorithm exploiting target structural constraints thorough template matching. Extended Lucas Kanade or ELK casts the original LK algorithm as a maximum likelihood optimization and then extends it by considering pixel object / background likelihoods in the optimization. Template matching and pixel-based object / background segregation are tied ...
متن کاملLucas Kanade Optical Flow Computation from Superpixel based Intensity Region for Facial Expression Feature Extraction
Analyzing facial expression video sequences is a challenging area in computer vision field. This is due to the fact that each of the expression has either one or more motions or positions of muscles beneath the skin of the face. It is also affected by occlusions and lighting conditions. Existing method in facial expression analysis either divide the face image into rectangular grid or as holist...
