matlab实现raw数据

要在MATLAB中实现对raw数据的处理，可以使用以下代码：

function image = readraw(filename)
    type = 'uint8';
    f1 = fopen(filename, 'r');
    data = fread(f1, type);
    fclose(f1);
    len = length(data);
    if len == 640*400
        M = 640;
        N = 400;
    else
        M = 1280;
        N = 800;
    end
    k = len/(M*N);
    image = reshape(data, M, N, k);
    image = transpose(image);
    image = fliplr(image);
end

function corrected = apply_cmatrix(im, cmatrix)
    if size(im, 3) ~= 3
        error('Apply cmatrix to RGB image only.')
    end
    r = cmatrix(1,1)*im(:,:,1) + cmatrix(1,2)*im(:,:,2) + cmatrix(1,3)*im(:,:,3);
    g = cmatrix(2,1)*im(:,:,1) + cmatrix(2,2)*im(:,:,2) + cmatrix(2,3)*im(:,:,3);
    b = cmatrix(3,1)*im(:,:,1) + cmatrix(3,2)*im(:,:,2) + cmatrix(3,3)*im(:,:,3);
    corrected = cat(3, r, g, b);
end

function colormask = wbmask(m, n, wbmults, align)
    colormask = wbmults(2) * ones(m, n);
    switch align
        case 'rggb'
            colormask(1:2:end, 1:2:end) = wbmults(1);
            colormask(2:2:end, 2:2:end) = wbmults(3);
    end
end

这段代码包含了三个函数。`readraw`函数用于读取raw文件并将其转换为图像数据。`apply_cmatrix`函数用于应用颜色矩阵对RGB图像进行校正。`wbmask`函数用于生成白平衡掩码。你可以根据需要调用这些函数来处理raw数据。
