在OpenCV 4中，`CV_HAAR_SCALE_IMAGE`被替换为`cv::CASCADE_SCALE_IMAGE`，因此您需要将代码中的`CV_HAAR_SCALE_IMAGE`替换为`cv::CASCADE_SCALE_IMAGE`。另外，在使用`cv::CascadeClassifier`类进行人脸检测时，需要确保已经正确加载了级联分类器，并且输入图像的颜色空间是灰度图像。下面是一个示例代...
Recently, convolution neural network based methods have dominated the remote sensing image super-resolution (RSISR). However, most of them own complex network structures and a large number of network parameters, which is not friendly to computational resources limited scenarios. Besides, scale ...
objects = cascade.detectMultisScale(image, scaleFactor, minNeighbors, flags, minSize, maxSize) cascade:已有的分类器对象; image:待分析的图像; scaleFactor:扫描图像时的缩放比例,可选参数; minNeighbors:每个候选区域至少保留多少个检测结果才可以判定为人脸,可选参数;值越大,分析的误差越小; flags:可选参数...
2.1.2 在bbox经过48net后,对所有尺度使用一次全局NMS,来去除bbox冗余,再送入48-calibration-net做人脸框校准;(After 48-net,NMS is applied globally to all detection windows at different scales to make most accurate detection window at the correct scale stand out and avoid redundant evaluation in the...
In the method, the MSRF and SMAP will be used to estimate motion parameters of the background of image sequence. From the result of simulation, we can conclude that the segmentation method is satisfactory.关键词: snake model cascade segmentation Multiscale Random Field global motion ...
