pixel value

Tea Color Sorter is an advanced device integrating with electrical, optical, mechanical, which uses the optical imaging of tea to get the pixel value and remove the defective goods by the pixel. It is widely used in agriculture and food industry.

茶叶色选机是指通过茶叶的光学信息成像得到像素值等对残次品进行剔除的一套集电学、光学、机械于一体的先进集成设备，广泛用于农业、食品业等。

The method does a bit-exclusive-or operation on each pixel with its prior one first. Then the bits of each pixel value is exchanged across, thereby the effect of image scrambling is improved again.

该算法首先根据每个像素和它前面相邻的像素进行按位异或运算，然后对其按照某种规则进行像素值的交叉换位，再次改变像素点的灰度值，从而提高图像置乱效果。

For wet soil on the extraction of the interference of the yellow pixel value in pictures, proposed combining S value of HSL color space to eliminate the color of wet soil.

针对图像中湿润土壤对提取黄色像素值的干扰，提出结合HSL颜色空间S分量消除湿土颜色。
