Boundary iou loss
WebApr 3, 2024 · Bounding box regression is the crucial step in object detection. In existing methods, while ℓn-norm loss is widely adopted for bounding box regression, it is not tailored to the evaluation metric, i.e., Intersection over Union (IoU). Recently, IoU loss and generalized IoU (GIoU) loss have been proposed to benefit the IoU metric, but still suffer … WebJun 26, 2024 · However, widely-used segmentation loss functions such as BCE, IoU loss or Dice loss do not penalize misalignment of boundaries sufficiently. In this paper, we propose a novel loss function, namely a …

WebOct 6, 2024 · Therefore, we employ IoU loss to measure boundary inconsistency. Accordingly a slight deviation would results in a small IoU loss, which ensures convergence. Let \(\mathcal {I}\) denote the set of pixels in the image. For every pixel p in the pixel set \(\mathcal {I}\), \(y_p\) corresponds to its output probability.
