如何用c语言在tc264上用数组对图像进行高斯模糊代码

以下是一个简单的C语言代码，用于在TC264上使用数组对图像进行高斯模糊：

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

#define WIDTH 640
#define HEIGHT 480

void gaussian_blur(unsigned char *input, unsigned char *output, int width, int height, float sigma)
{
    int i, j, k, r;
    float *kernel, *p, sum;
    unsigned char *src, *dst;

    kernel = (float*)malloc((2 * r + 1) * sizeof(float));
    sum = 0.0;
    for (i = 0; i < 2 * r + 1; i++) {
        kernel[i] = exp(-(i - r) * (i - r) / (2 * sigma * sigma));
        sum += kernel[i];
    }
    for (i = 0; i < 2 * r + 1; i++) {
        kernel[i] /= sum;
    }

    for (i = 0; i < height; i++) {
        for (j = 0; j < width; j++) {
            sum = 0.0;
            p = kernel;
            src = input + i * width + j - r;
            dst = output + i * width + j;
            for (k = 0; k < 2 * r + 1; k++) {
                if (j - r + k >= 0 && j - r + k < width) {
                    sum += *p * src[k];
                }
                p++;
            }
            *dst = (unsigned char)sum;
        }
    }

    free(kernel);
}

int main()
{
    unsigned char *input, *output;
    FILE *fp;
    int i, j;

    input = (unsigned char*)malloc(WIDTH * HEIGHT * sizeof(unsigned char));
    output = (unsigned char*)malloc(WIDTH * HEIGHT * sizeof(unsigned char));

    fp = fopen("input.raw", "rb");
    fread(input, sizeof(unsigned char), WIDTH * HEIGHT, fp);
    fclose(fp);

    gaussian_blur(input, output, WIDTH, HEIGHT, 1.0);

    fp = fopen("output.raw", "wb");
    fwrite(output, sizeof(unsigned char), WIDTH * HEIGHT, fp);
    fclose(fp);

    free(input);
    free(output);

    return 0;
}

请注意，这只是一个简单的示例代码，您可能需要根据您的具体需求进行修改。
