视觉功能像素计数器（Pixel Counter）是一个用于计数像素并从中提取特征的功能。
像素计数器可以通过简单的操作定义区域，在该区域内对符合预定灰度值区间（ThresholdMin/Max）的像素进行计数。

本节主题
.Vision function Pixel Counter is a function for counting pixels and extracting features from them.
Pixel Counter allows, through simple operation, regions to be defined within which the pixels that correspond to a predefined grayscale value interval (ThresholdMin/Max) are counted.

Based on these defined parameters, counting and statistical analysis of the searched pixels can be performed in cyclic operation.
For an overview of the registers used by Pixel Counter, see section Overview of registers .
