3. 7. 4, is presented below in a step-wise approach. Step 1: The time required to resize image into a 1024 × 768 size image is O (n) , where n is the number of pixels in the image. Step 2: Computational time required for checking image stability using T-test is O(n) . Step 3: In the worst case, the computational time required to split the image is O(1) × O (n) = O (n) . Step 4: To calculate the Rmap which is used to map the pixels into a region, requires O(n) computational time. O(n) computational time.

Region accepting stage find three types of regions: accepted region, partially accepted region, and rejected region. Accepted region is the region that contains only foreground Block Based Image Segmentation 19 pixels while partially accepted region has pixels of both foreground and background. The partially accepted regions need to be replaced by the best match pattern and after replacing it will be treated as an accepted region. The rejected region is the background of the image and is not being replaced by a matched pattern.

The region stability test is applied in both steps to decide whether the region is stable or not. If the image is found unstable it is subdivided into 12 equal and square sub-regions [7]. Split Stage – 2: After the completion of the split stage-1, split stage-2 is applied. In this stage each square region is recursively subdivided into 4 sub-regions by applying the T-test. After completing of the split stage, the regions are matched with the patterns called micro-blocks (MBs) in region accepting stage which is detailed in the following section.
