Average Precision (AP) is defined and measured according to standard MS COCO evaluation procedure.
im_data , shape: [1x3x480x480] - An input image in the format [1xCxHxW]. The expected channel order is BGR.im_info, shape: [1x3] - Image information: processed image height, processed image width and processed image scale w.r.t. the original image resolution.classes, shape: [100, ] - Contiguous integer class ID for every detected object, '0' for background, i.e. no object.scores: shape: [100, ] - Detection confidence scores in range [0, 1] for every object.boxes, shape: [100, 4] - Bounding boxes around every detected objects in (top_left_x, top_left_y, bottom_right_x, bottom_right_y) format.raw_masks, shape: [100, 81, 28, 28] - Segmentation heatmaps for all classes for every output bounding box.[*] Other names and brands may be claimed as the property of others.
