Initialization method.
- 参数:
mllm_mapper_args -- Arguments for multimodal language model mapper. Controls the generation of captions for bounding box regions. Default empty dict will use fixed values: max_new_tokens=256, temperature=0.2, top_p=None, num_beams=1, hf_model="llava-hf/llava-v1.6-vicuna-7b-hf".
image_text_matching_filter_args -- Arguments for image-text matching filter. Controls the matching between cropped image regions and text descriptions. Default empty dict will use fixed values: min_score=0.1, max_score=1.0, hf_blip="Salesforce/blip-itm-base-coco", num_proc=1.
yoloe_path -- The path to the YOLOE model.
iou_threshold -- We consider two bounding boxes from different models to be overlapping when their IOU score is higher than the iou_threshold.
matching_score_threshold -- If the matching score between the cropped image and the character's name exceeds the matching_score_threshold, they are considered a match.
