What is pixel based motion estimation?
In our algorithm, the motion vector for each pixel is calculated with respect to estimate translation, scale, and rotation transforms. The motion relationships between neighboring pixels are considered via the Markov random field model to improve the motion estimation accuracy.
Which is the most popular method for practical motion estimation?
1.3 Optical Flow. Optical flow, or motion estimation, is a fundamental method of calculating the motion of image intensities, which may be ascribed to the motion of objects in the scene. Optical flow is an extremely fundamental concept that is utilized in one form or another in most video-processing algorithms.
What is the motion estimation techniques in video-processing?
There are two mainstream techniques of motion estimation: pel-recursive algorithm (PRA) and block-matching algorithm (BMA). PRAs are iterative refining of motion estimation for individual pels by gradient methods. BMAs assume that all the pels within a block has the same motion activity.
What are the applications of motion estimation techniques?
Motion estimation is an important process in a wide range of disciplines and applications, such as image sequence analysis, computer vision, target tracking, and video coding. Different disciplines and applications have different requirements and may, therefore, use different motion estimation techniques.
