This procedure applied to the PSPNet  could improve the mean Intersection over Union (abbr. mIoU) of the Cityscapes data set from 79.4 to 80.6 %. The higher computational effort of this approach represents a considerable expenditure of time, depending on the image resolution. To the best of the authors’ knowledge, a confidence-based com-
The intersection-over-union (IoU) is usually used to measure the performance of any ob-ject category segmentation method. In this paper, we propose an approaches have been proposed for semantic segmentation that take advantage of high-level representation of images obtained from DNNs.
Jun 08, 2018 · Visually, the semantic segmentation results overlap well for classes such as road, sky, and building. However, smaller objects like pedestrians and cars are not as accurate. The amount of overlap per class can be measured using the intersection-over-union (IoU) metric, also known as the Jaccard index. Use the jaccard function to measure IoU.

Sep 12, 2017 · Region Similarity: defined as the intersection-over-union between the estimated segmentation and the ground truth mask. Contour Accuracy is the F-measure for the contour based precision and recall Contour Accuracy: interprets the masks as a set of closed contours and computes the contour-based F-measure which is a function of precision and recall.
