边缘检测算法Verilog实现的

在采用DCT块压缩标准的图像或视频流中，块效应是一个严重的问题，因此，能够有效地检测并去除块效应逐渐成为人们关注的焦点。而本文基于此目的，提出了一种DCT域的块效应盲测量和去块效应算法，利用HVS和块效应模型估测块效应，进而自适应地去除检测到的块效应。通过实验仿真证实了该算法的有效性，另外其低复杂度，可以在实时视频或图像监控领域得到应用。 基本原理可以分为块效应的盲测量和去块效应两部分。

帧差法的源代码，为c++语言编写，属于图像处理类，并用最新 Mat格式 编写。 帧差法就是在图像序列相邻两帧或三帧间采用基于像素的时间差分通过闭值化来提取出图像中的运动区域。 首先，将相邻帧图像对应像素值相减得到差分图像，然后对差分图像二值化，在环境亮度变化不大的情况下，如果对应像素值变化小于事先确定的阂值时， 可以认为此处为背景像素:如果图像区域的像素值变化很大，可以认为这是由于图像中运动物体引起的，将这些区域标记为前景像素，利用标记的像素区域可以确定运动目标在图像中的位置。

StereoLithography(StL) is something that is widely used in CAD/CAM, RapidPrototyping etc. The concept is that any surface or solid is exported to StL format by data exchange packages after they are modeled in commercial CAD packages. This data consists of triangulated facets that approximate the surface of the solid. No topological or geometric information is exported. The surface is subdivided into small triangles. The approximation uses chordal deflection for curved surfaces to smoothen the surface. More the smoothening required, more number of smaller triangles are generated by subdivision resulting in larger size of data file. Now, along with triangles, their facet normals are also generated. The data is written both in ASCII and binary formats. The data in ASCII is written like this:

本代码完全使用自己编写的代码实现canny算子提取边缘，并与MATLAB自带的canny算法进行比较，

能够得到双目摄像机的差异图，用于提取两幅图的深度信息。通过匹配，计算时差，由时差和深度的关系，计算得到深度信息。差异图的计算中，匹配采用块匹配，计算为差异信息，增加了能量函数作为度量。输入参数为视差范围。
