基于MATLAB平台工作，对图像文件中的果实（类圆形果实）进行识别，通过图像灰度化，二值化，提取边缘，Hough变换等一系列步骤后，对果实图像进行特征提取以获取所需信息。通过对边缘的提取识别图像，便于机器识别。-Work based on MATLAB, the fruit image files (class round fruits) identify the image gray value, edge extraction, Hough transform a series of steps on fruit image feature extraction to obtain the required information. Through the extraction on the edge of the identification image, to facilitate the identification of the machine.
