Texture Flow Analysis

Matlab code I wrote for an orientational sensitive texture filter.

Quick start

This repository implements an orientation-sensitive texture filter for local motion analysis in Matlab. See DEPENDENCIES.md for the Image Processing Toolbox requirement. Each script prompts interactively for its input image(s); sample images to try them on are in media/.

Repository contents

• textureFilter.m -- the main function; computes local motion orientation based on the Jacobian matrix and displays it with streaks and a directional color-coded map.
• accumulator.m -- builds a streak-accumulator image over a stack of images, using defineStackNames.m and getFilenameBody.m.
• fsmPrepScaleSpace.m -- a standalone scale-space / edge-detection script.
• Gauss2D1.m -- a Gaussian-filter helper used by textureFilter.m.
• media/ -- sample/example images.
• License: see LICENSE -- research/educational use.

About

The textureFilter.m function computes the local motion orientation based on the Jacobian matrix and displays it with streaks, and a directional color-coded map.
