    说明:  是一本关于C语言跟单片机接口的书,还可以.反正我看了很好.不知道是否适合你.(Is on a single-chip interface with C language book, also. Anyway, I saw very good. Do not know if for you.)

    为了研究植物的生长规律,应用数字摄影图像处理法对山楂叶面积进行无损测量,该方法采用数码相机在田间获取山楂叶子的数字图像,对所拍图像进行背景去除、二值化及中值滤波处理,然后利用Matlab软件编程.快速计算出叶子的面积。把这一面积同常用的叶纸称重法所测面积进行比较.结果基本相同,由此可见,数字摄影图像法测量叶面积,具有简单、准确、方便快捷的特点.这对数字农业的植物信息快速采集和利用具有重要的意义。 ( In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of hawthorn leaves in the field, on the film image background removal, binarization and medianfiltered, and then using the Matlab software programming. Quickly calculate the area of the leaves. This area with the common leaf paper weighing measured by the area to compare. The results are basically the same, shows, digital photographic images method to measure leaf area, with a simple, accurate, and convenient features. This rapid acquisition and use of digital agricultural plant is of great significance.
