### Producing images with subpixel shift in region of interest

Let's say for a zebra image, and at certain pixel location, I would like to makes it "vibrate/warp" to and fro in horizontal direction at a certain frequencies in a sequence of images of time ...

### How do I derive complicated robotic motion models easily?

I have a filter that tracks a robot. I want it to use a 2D coordinated turn polar velocity motion model (from page 15 here): But I want to expand on this motion model: I want an additional velocity ...

### Does Gamma Correction Interfere with Sub Pixel Motion Estimation?

Advanced Video Coding (AVC) and High Efficiency Video Coding (HEVC) work on gamma corrected, non linear, colors. When interpolating the value at subpixels, a multi tap algorithm processes the gamma ...

### Obtaining Correct (Least Squares Sense) Affine Transform Parameters Between Two Images

I have two images that I want to compute the affine motion model parameters. The model that I use is $$x' = a_1x+a_2y+a_3$$ $$y' = a_4x+a_5y+a_6$$ To calculate those 6 parameters, I picked 6 points (...

### What motion estimation techniques that could estimate the motion of every pixel?

I'm trying to estimate a motion from a video, however based on my finding, those methods usually meant for large motion and sparse in nature. Optical flow: Sparse and fail to detect sub-pixel motion ...

### Possible ways to determine the direction of moving object?

I'm trying to determine the moving direction of an object in x-axis only. Figure below shows part of my effort. However, I got stuck. As you can see from the middle image, the green represent the dot ...

### Classify type of motion using decision trees and features

Consider a decision tree for separating between the following activities: Sitting, Driving, Running, Walking. Assume that you are given the following features: Dominant frequency (F1), meanX, meanY, ...
