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

Description: Matlab下的实时跟踪程序，内附demo程序，也可以选择手动选择跟踪区域，这种方式需要将demo中的一段代码前的注释去掉-Main file: Tracking_PLS.m
You can set the initial position of the target object with know parameters or select the target region manually in the first frame.
You can tune the \Sigma parameter for particle filtering to obtain better results.
You can also test the PLST1 method mentioned in our paper which is named "Tracking_PLST1.m".

Description: is Matlab code implements a new level set formulation, called distance regularized level set evolution (DRLSE), proposed by Chunming Li et al s in the paper "Distance Regularized Level Set Evolution and its Application to Image Segmentation", IEEE Trans. Image Processing, vol. 19 (12), 2010
The main advantages of DRLSE over conventional level set formulations include the following: 1) it completely eliminates the need for dreinitialization 2) it allows the use of large time steps to significantly speed up curve evolution, while ensuring numerical accuracy 3) Very easy to implement and computationally more efficient than conventional level set formulations.
This package only implements an edge-based active contour model as one application of DRLSE. More applications of DRLSE can be found in other published papers in the following website:

MATLAB has the capability of running functions written in C. The files which hold the source
for these functions are called MEX-Files. Some functions of our codes are written in C.
The purpose of this software is to implement the MCVEM algorithm, described in the paper
mentioned above, when applied to Image Segmentation. MCVEM consists in combining approximation
techniques - based on variational EM - and simulation techniques - based on MCMC
-.
This software is the first version that is made publicly available.

which has the following features:
1. Depth maps are interpreted according to the MPEG Informative
Recommendations in MPEG Doc. N8038.
2. Left image is rendered Right most pixel to the Left most pixel and Right Image is rendered vice versa. This is done to make sure that no background pixels would appear as foreground.
3. Disocclusions are filled with Background pixel extrapolation,
however with some small modifications. Disocclusions are filled in the opposite direction to rendering.
