SSD : Understanding single shot object detection. Classic object detectors are based on sliding window approach (DPM), which is computationally intensive due to the exhaustive search but is rapidly rendered obsolete by the rise of region proposals with (R-CNN, Fast R-CNN), this approach … Protobufs are a language neutral way to describe information. Given a collection of images with a target object in many different shapes, lights, poses and numbers, train a model so that given a new image, a bounding box will be drawn around each of the target objects if they are present in the image. In order to improve the detection rate of the traditional single-shot multibox detection algorithm in small object detection, a feature-enhanced fusion SSD object detection algorithm based on the pyramid network is proposed. Random sampling from beta-distribution is slightly better than 0,5:0.5 fixed even mixup. GitHub is where people build software. ...
