A Biological Hierarchical Model Based Underwater Moving Object Detection

Algorithm 1

Hierarchical background modeling algorithm.
Input: Underwater image sequence
Step  1. Segment each frame of input underwater image sequence into multiple nonoverlapped
Step  2. Extract intensity features of each subblock, ;
Step  3. Establish the background model based on each subblock to distinguish background and
  rough object;
Step  4. Update parameters for the background model;
Step  5. Extract the texture features of each pixel in rough object region, ;
Step  6. Build background model based on each pixel to obtain object contours.
Output: Results of moving objects detection
