In the field of computer vision, CVPR (ComputervisionandPattern Recognition) is a very famous conference. However, the question of "how much the score is positive" is a bit vague, because CVPR usually accepts or rejects papers based on their quality, originality and contribution, rather than scores. If you mean an evaluation method or a specific scoring standard in computer vision tasks, such as object detection or image segmentation, you may need a clearer context to answer.
