android - Opencv Android 的代码优化

Question

我在 Android 上使用此 opencv 代码进行强度均衡。每帧 (720x480) 的执行时间约为 300 毫秒。有人对可能的时间优化有想法吗？

这是代码:

        cvtColor(image, hsvImage, CV_BGR2HSV);
        // Get intensity
        intensity = hsvImage.at<Vec3b>((int)reference.Point_::y, (int)reference.Point_::x);
        float value = (float)REGULAR_INTENSITY / intensity[2];
        float saturation = (float)REGULAR_SATURATION / intensity[1];
        if (counter == 15 && (int)intensity[2] < REGULAR_INTENSITY) {
            equalization = false;
        }
        // Modify intensity
        float transformedSaturation, transformedValue;
        for(int i = 0; i < hsvImage.rows; i++) {
            unsigned char *data = hsvImage.ptr(i);
            for(int j = 0; j < hsvImage.cols; j++) {
                transformedSaturation = (uchar)*++data * saturation;
                if (transformedSaturation > MAX_COLOR) {
                    transformedSaturation = MAX_COLOR;
                }
                *data++ = transformedSaturation;
                transformedValue = (uchar)*data * value;
                if (transformedValue > MAX_COLOR) {
                    transformedValue = MAX_COLOR;
                }
                *data++ = transformedValue;
            }
        }
        cvtColor(hsvImage, image, CV_HSV2BGR);

您尝试过使用 OpenCV transform ？我想它是优化的，但我不知道饱和度(即如果> max_color，则= max color)
