# 3. Image Data Analysis

In image processing, the analysis of image pixel data is crucial as it helps us understand the characteristics and content of images. This section will introduce the structural analysis of image data, pixel color extraction and analysis, and image data statistics and processing algorithms.

### 3.1 Image Data Structure Analysis

In C language, image data is typically stored in the form of a two-dimensional array, ***mon image data structures include RGB, RGBA, etc., which represent the red, green, and blue color channels, and RGBA also includes an alpha (transparency) channel.

### 3.2 Pixel Color Extraction and Analysis

By reading image pixel data, we can extract color information for each pixel point and then perform various analyses. For example, we can count the number of pixels of each color, identify the most common color, or perform color space transformations.

### 3.3 Image Data Statistics and Processing Algorithms

For the statistics and processing of image data, common algorithms include grayscale processing, edge detection, and image filtering. These algorithms can process images in various ways, extract interesting feature information, and prepare for subsequent applications.
