示例1: RunCannyTest
void Test::RunCannyTest(const RGBImage* in) {
Gaussian smoother;
Sobel sobel;
Canny canny;
StudentPreProcessing converter;
double sigma = 1.6;
int kernelSize = 5;
// Convert RGB to Intensity
IntensityImage* grey = ImageFactory::newIntensityImage(in->getWidth(), in->getHeight());
grey = converter.stepToIntensityImage(*in);
BaseTimer timer;
int total = 0;
for (int i = 0; i < 10; ++i) {
timer.start();
/* Start of Canny */
// 1. Smooth Intensity with Gaussian
IntensityImage* gaussian = ImageFactory::newIntensityImage(in->getWidth() - kernelSize, in->getHeight() - kernelSize);
smoother.smoothImage(grey, gaussian, sigma, kernelSize);
// 2. Find edges with Sobel (convolve X and Y separately for Canny)
int sobelKernelSize = 3;
IntensityImage* sobelX = ImageFactory::newIntensityImage(gaussian->getWidth() - sobelKernelSize, gaussian->getHeight() - sobelKernelSize);
IntensityImage* sobelY = ImageFactory::newIntensityImage(gaussian->getWidth() - sobelKernelSize, gaussian->getHeight() - sobelKernelSize);
sobel.filterXY(gaussian, sobelX, sobelY);
// 3. Apply non-maximum suppresion
IntensityImage* nonMaxSuppression = ImageFactory::newIntensityImage(sobelX->getWidth(), sobelX->getHeight());
canny.nonMaximumSurpression(sobelX, sobelY, nonMaxSuppression);
// 4. Apply hysteresis threshold
IntensityImage* hysteresisThreshold = ImageFactory::newIntensityImage(sobelX->getWidth(), sobelX->getHeight());
canny.threshold(nonMaxSuppression, hysteresisThreshold, 60, 70);
timer.stop();
std::cout << timer.elapsedMilliSeconds() << " ms" << std::endl;
total += timer.elapsedMilliSeconds();
timer.reset();
if (i == 9)

}
std::cout << "Average time per Canny edge detection: " << (total / 10) << " ms" << std::endl;
