Computation Optical Flow Using Pipeline Architecture
Accurate estimation of motion from time-varying imagery has been a popular problem in vision studies, This information can be used in segmentation, 3D motion and shape recovery, target tracking, and other problems in scene analysis and interpretation. We have presented a dynamic image model for estimating image motion from image sequences, and have shown how the solution can be obtained from a ...
متن کاملCS6320 Final Project: Image Sequence Stabilization with Optical Flow
Image sequence stabilization is widely used in many fields related to photography. In this project, we propose a three-step method to compensate for the influence of camera shake. First, we estimate the motion field with a state-of-the-art optical flow method; then the transformation parameter matrices between each two consecutive images are computed; finally, the whole image sequence is stabil...
متن کاملتحلیل حرکت جریانات دریائی در تصاویر حرارتی سطح آب دریا
Oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. For instance Sea Surface Temperature (SST) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. The purpose of this thesis is to derive a relatively complete frame...
متن کاملUsing Optical Flow to Reduce Noise in Image Sequences
In this paper we propose a method for noise reduction in image sequences, based on the optical flow, consisting in tracking each pixel’s position in the previous and following images. In some cases the optical flow imperfections can cause artifacts. To prevent them we also propose an improvement to the method based on the estimation of the imperfections of the optical flow. Using that estimatio...
متن کاملOptical flow estimation using high frame rate sequences
Gradient-based optical flow estimation methods such as LucasKanade method work well for scenes with small displacements but fail when objects move with large displacements. Hierarchical matching-based methods do not suffer from large displacements but are less accurate. By utilizing the high speed imaging capability of CMOS image sensors, the frame rate can be increased to obtain more accurate ...
