A Novel Merging Criterion Incorporating Boundary Smoothness and Region Homogeneity for Image Segmentation-Abstract
A novel joint region merging criterion combining region homo-geneity and boundary smoothness is proposed. Previous watershed segmentation method which utilizes region homogeneity or edge integrity or both gives good results in some cases. However, for complex scenes such as images of a vehicle with irregular roadside objects reflected on the window panes, it tends to give undesired segmentation results with region boundaries not residing on real physical boundaries. Aiming at improving the segmentation of these complex scenes, we propose the incorporation of an additional measure of boundary smoothness into a new joint criterion. Based on this, an affine transform invariant measure of the smoothness of boundaries is developed, which is the equivalent width of the energy distribution function over frequencies, obtained from Fourier descriptors of the boundary. Experimental results and evaluation are presented in this paper to demonstrate the merits of the proposed method.

Description: This code demomstrates an improved algorithm based on the local binary fitting (LBF) model
in Chunming Li et al s paper:
"Minimization of Region-Scalable Fitting Energy for Image Segmentation",
IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008.
Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows.
Run the Demos in the M-files for several test images. Once an image comes out, click
the mouse to generate a polygon as the initial contour: left click to get
a number of points, then right click to get the end point.
The number of iterations may need to be increased if the initial contour is too far
away from the desired object boundary. -This code demomstrates an improved algorithm based on the local binary fitting (LBF) model

Take a variety of JPEG encoding, includes length coding (Run Length Coding) and Huffman (Huffman) coding, a high compression ratio. In the code before the data block, discrete cosine transform (DCT) and quantization, to retain a large low-frequency signal energy, discarding high-frequency signals in order to achieve compression.
