Web12 apr. 2024 · RCNN主要有4个步骤： 1、候选区域的生成：输入进去一张图片，使用Selective Search方法，将一张图片中生成2000个候选区域。 2、特征提取：生成的候选区域大小不一样，那就全都resize到一样的大小，比如64*64的，将这些候选区域送到CNN网络中提取特征。 3、类别判断：提取特征后，然后将这些特征送入20个SVM分类器中，注 … WebIntersection Over Union (IuO) threshold is used in object detection to define positives and negatives. If the IoU threshold is low, then the object detector tends to produce many noisy detections. However, increasing the IoU threshold degrades the performance of the detector.
