Gradient information serves several purposes. It can relate the structure of objects in an image, identify features of interest for recognition/classification directly or provide the basis of further processing for various computer vision tasks. For example, "edges," noted by regions of high gradient magnitude, are central to the task of identifying defects in circuitry. A sample "edge-detected" image using the Image Processing Toolbox for MATLAB is shown where locations marked by white are those points that are indicative of high gradient magnitude, which can also be described as regions of high pixel contrast.

小波算法，用于对红外光谱或者拉曼光谱数据进行降噪和去背景等处理。(Wavelet algorithm for the Infrared or Raman spectral data to background processing and noise reduction.)

数字减影(DSA:Digital Subtract Angiography)是一种传统的血管可视化技术[1]。这一技术用注射造影剂后的活动图像减去注射造影剂前记录的掩模图像来显示不透明的血管。其期望的结果是在减影后的图像上背景结构被完全消除。(estimation based on background)
