matlab计算二值图像几何特征中目标主轴长度(binary image matlab calculation of the geometric characteristics of the target length of major axis)

利用八方向的sobel边缘检测，实现对图像多梯度的梯度检测，检测出的边缘信息更加平滑连续。(Eight direction Sobel edge detection is used to realize gradient detection of image multi gradient, and the edge information detected is more smooth and continuous.)

计算Zernike矩，对图像进行了平移，尺度归一化(Computing Zernike moments, the image of the translation, scaling normalization)

说明：  图像的超分辨率重建程序，matlab程序，很不错，需要的朋友请下载。(Image super-resolution reconstruction program, matlab program, very good friends in need, please download.)

简单起见，这里设定阈值为122，即最大灰度的一半(the sake of simplicity, this threshold value is set to 122, the largest gray half)

超像素分割方法，在计算机视觉领域，图像分割（Segmentation）指的是将数字图像细分为多个图像子区域（像素的集合）（也被称作超像素）的过程。超像素有一系列位置相邻且颜色、亮度、纹理等特征相似的像素点组成的小区域。这些小区域大多保留了进一步进行图像分割的有效信息，且一般不会破坏图像中物体的边界信息。(Super pixel Segmentation method, in the field of computer vision, image Segmentation, Segmentation) refers to the digital image Segmentation region for multiple image sequence (the set of pixels) (also known as the pixels) process. Adjacent pixels have a series of position and features such as color, brightness, texture similar to that of small region composed of pixels. Most of these small area retains the further effective information for image segmentation, and generally does not destroy the boundary of the object in the image information.)
