  高斯滤波是一种线性平滑滤波,适用于消除高斯噪声,广泛应用于图像处理的减噪过程。通俗的讲,高斯滤波就是对整幅图像进行加权平均的过程,每一个像素点的值,都由其本身和邻域内的其他像素值经过加权平均后得到。高斯滤波的具体操作是:用一个模板(或称卷积、掩模)扫描图像中的每一个像素,用模板确定的邻域内像素的加权平均灰度值去替代模板中心像素点的值。(Gaussian smoothing filter is a linear filter for the elimination of Gaussian noise, the noise reduction process is widely used in image processing. Popular speaking, a Gaussian filter to the whole image is a weighted average of the process, the value of each pixel, both by itself and other neighborhood pixel values obtained after weighted average. The specific operation Gaussian filter is: a template (or a convolution mask) to scan each pixel in the image, a weighted average gray value of the neighborhood is determined using a template to replace the pixel value of the center pixel of the template.)

    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.
