Detailed semantic segmentation evaluation index

This article mainly introduces the three evaluation indicators of semantic segmentation, namely execution time, memory usage, and accuracy. This article focuses on accuracy.

1. Execution time

2. Memory usage

3. Accuracy

Suppose there are k+1 categories (including k target categories and 1 background category);

1、Pixel Accuracy (PA)

2、Mean Pixel Accuracy (MPA)

3、Mean Intersection over Union（MIoU）

4、Frequency Weighted Intersection over Union (FWIoU)
