图像自适应阈值分割，基于直方图的图像阈值分割(Image adaptive threshold segmentation)

使用matlab进行图像去雾，有助于帮助刚入门的图像小白学习matlab图像处理(Matlab image defogging, helpful to help beginners learning image white matlab image processing)

说明：  考虑DCT阈中量化效应，采用8X8的DCT模板，选择量化步长，结合缩放因子进行图像压缩。(Considering the quantization effect in DCT threshold, we use the 8X8 DCT template, select the quantization step, and combine the scaling factor to compress the image.)

自己画的一条简单的Bezier曲线，通过四个控制点（控制点可自行选取）(She painted a simple Bezier curve through four control points (control points can be selected as their own))

a.牌照定位，定位图片中的牌照位置； b.牌照字符分割，把牌照中的字符分割出来； c.牌照字符识别，把分割好的字符进行识别，最终组成牌照号码。 (a. License Plate Location, location location of the picture of the license b. Character Segmentation license to license the characters split up c. license character recognition, to split a good character to identify the final composition of license number. )

基于lloyd-max最佳量化器的量化程序，如有需要可随时下载。(Based on the best lloyd-max quantizer quantization procedure, if necessary, at any time to download.)

基于Gabor 变换的地震反褶积正反变换程序，以及和维纳反褶积的对比程序 (Gabor transform based on seismic deconvolution forward and reverse transform procedures, and the Wiener deconvolution of the comparison program)

实现通过用户给定B样条曲线的控制顶点、设定B样条曲线的次数及类型，进而绘制出相应的B样条曲线和对应的基函数图形。并且可以通过鼠标拖拽控制顶点修改B样条曲线和对应的基函数图形。从而，对B样条曲线和基函数的性质有更深入更直观的了解，理解B样条曲线和基函数的对应关系，在以后的学习中能更好地运用B样条曲线。(The number and type of user to achieve a given control vertices B-spline curve, set the B-spline curves, and then draw the corresponding B-spline basis functions and the corresponding graphic. And can be modified by dragging the mouse to control the apex B-spline curves and the corresponding basis function graphics. Thus, the nature of the B-spline curves and basis functions have a deeper and more intuitive understanding, understanding of the correspondence between the B-spline curves and basis functions in later learning to better use of B-spline curves.)

说明：  基于小波的图像质量评价方法，具有一定借鉴意义。(Wavelet-based image quality assessment method, with some reference.)
