To evaluate object detection models like R-CNN and YOLO, themean average precision (mAP)is used. The mAP compares the ground-truth bounding box to the detected box and returns a score. The higher the score, the more accurate the model is in its detections. In my last article we looked ...
1.BPR(Best Possible Recalls) 《FCOS: Fully Convolutional One-Stage Object Detection》 BPR is defined as the ratio of the number of ground-truth boxes a detector can recall at the most divided by all ground-truth boxes. A ground-truth box is considered being recalled if the box is assigned...

:mAP (mean Average Precision) for Object Detection | by Jonathan Hui | Medium In the figure above, AP@.75 means the AP with IoU=0.75. mAP (mean average precision) is the average of AP. In some context, we compute the AP for each class and average them. But in some context, they ...

Advances in microscopy hold great promise for allowing quantitative and precise measurement of morphological and molecular phenomena at the single-cell level in bacteria; however, the potential of this approach is ultimately limited by the availability of methods to faithfully segment cells independent of...
It is initially developed for military purposes and also used for many other applications such as law enforcement, hunting, surveillance, security, navigation, and hidden object detection1. Night vision technology basically works on the Infrared (IR) spectrum2. Thus, for monitoring objects in dark ...

If the bounding box is also associated with a confidence score for ranking, use theevaluateObjectDetectionfunction. example [precision,recall] = bboxPrecisionRecall(bboxes,groundTruthBboxes,thresho...
In this study, we propose a blind obstacle detection system based on the PC-CS-YOLO model. The system improves the backbone network by adopting the partial convolutional feed-forward network (PCFN) to reduce computational redundancy. Additionally, to enhance the network's robustness in multi-scale...
