基于小波变换的图像分割算法，它实现了论文 Wavelet Based Bimodal Image Segmentation for Blob Exctraction... 的算法。(This code is a part of work Wavelet Based Bimodal Image Segmentation for Blob Exctraction... .)

自动图像拼接，利用SIFT特征匹配算法，RANSAC(random sample consensus)算法，加权平滑算法等技术克服了传统图像拼接技术中的局限性(如光照、尺度变化的影响等)，实现了光照和尺度变化条件下的多视角无缝图像拼接(Automatic Image Stitching  Local features detection  Features Matching  Homography Estimation RANSAC Image blending )

说明：  图像的灰度图，和计算梯度的matlab代码实现(Grayscale image, and computing gradient)

图象处理中经常用到图象抽取和插值，本程序就是常用的双线性插值法的实现(image processing frequently used images collected and interpolation, the procedure is commonly used by the bilinear interpolation to achieve)

说明：  k-svd算法用于稀疏表示的图像去噪，字典学习算法，去噪效果良好(k-svd algorithm for image denoising of sparse representation)

本程序实现了两种误差扩散算法，分别用Sierra扩散滤波器和stenenson扩散滤波器，实现了比Floy_stein更好的误差扩散半色调效果。(This procedure implements two error diffusion algorithm, respectively Sierra diffusion filters and stenenson diffusion filter, to achieve better than Floy_stein error diffusion halftone effects.)

说明：  用于物体目标轮廓的提取与跟踪，能更好的识别出物体轮廓。(Target contour for object extraction and tracking, to better identify the contours of objects.)
