Object-Wise Just Recognizable Distortion Dataset

We selected 8,961 images from COCO2017 as source images. Then, these source images were coded and decoded by the general VVC codec, i.e., VTM14.0, with 64 QPs and All-Intra configuration. 64 distorted versions were generated for each source image. Secondly, we detected objects on both the source and distorted images using Faster R-CNN configured with ResNet-101 to generate object labels. Meanwhile, a threshold Tobject was set as 0.9 to ensure all objects were detected with a confidence higher than 90%. There are totally 29,218 objects detected from 8,961 images. Thirdly, three utilities are used to evaluate the performance of object detection, including bounding box, confidence and category.
