bayer RAW24 线性插值转彩 c++

以下是使用C++进行Bayer RAW24线性插值转彩的示例代码：

#include <iostream>
#include <vector>

// 线性插值函数
int linearInterpolation(int a, int b, int c, int d) {
    return (a + b + c + d) / 4;
}

// Bayer RAW24线性插值转彩函数
void bayerToRGB(std::vector<unsigned char>& bayerData, int width, int height, std::vector<unsigned char>& rgbData) {
    int rgbWidth = width * 3;
    int rgbHeight = height * 3;
    rgbData.resize(rgbWidth * rgbHeight);

    for (int y = 0; y < height; y++) {
        for (int x = 0; x < width; x++) {
            int bayerIndex = y * width + x;
            int rgbIndex = (y * 3) * rgbWidth + (x * 3);

            // 获取周围像素的索引
            int leftIndex = y * width + (x - 1);
            int rightIndex = y * width + (x + 1);
            int topIndex = (y - 1) * width + x;
            int bottomIndex = (y + 1) * width + x;

            // 获取周围像素的值
            int leftPixel = (x > 0) ? bayerData[leftIndex] : 0;
            int rightPixel = (x < width - 1) ? bayerData[rightIndex] : 0;
            int topPixel = (y > 0) ? bayerData[topIndex] : 0;
            int bottomPixel = (y < height - 1) ? bayerData[bottomIndex] : 0;

            // 进行线性插值
            int red = linearInterpolation(leftPixel, rightPixel, topPixel, bottomPixel);
            int green = bayerData[bayerIndex];
            int blue = linearInterpolation(topPixel, bottomPixel, leftPixel, rightPixel);

            // 将RGB值写入输出数据
            rgbData[rgbIndex] = red;
            rgbData[rgbIndex + 1] = green;
            rgbData[rgbIndex + 2] = blue;
        }
    }
}

int main() {
    // 假设有一个Bayer RAW24数据
    std::vector<unsigned char> bayerData = { /* Bayer RAW24数据 */ };
    int width = 640;
    int height = 480;

    // 调用Bayer RAW24线性插值转彩函数
    std::vector<unsigned char> rgbData;
    bayerToRGB(bayerData, width, height, rgbData);

    // 输出转换后的RGB数据
    for (int i = 0; i < rgbData.size(); i += 3) {
        std::cout << "R: " << (int)rgbData[i] << ", G: " << (int)rgbData[i + 1] << ", B: " << (int)rgbData[i + 2] << std::endl;
    }

    return 0;
