| Welcome to the SAM-HQ demo <br/> | |
| You may select different prompt types to get the output mask of target instance. | |
| ## Usage | |
| You may check the instruction below, or check our github page about more details. | |
| <details> | |
| You may select an example image or upload your image to start, we support 4 prompt types: | |
| **automatic**: Automaticly generate text prompt and the corresponding box input with BLIP and Grounding-DINO. | |
| **scribble_point**: Click an point on the target instance. | |
| **scribble_box**: Click on two points, the top-left point and the bottom-right point to represent a bounding box of the target instance. | |
| **text**: Send text prompt to identify the target instance in the `Text prompt` box. | |
| We also support a hyper-paramter **hq_token_only**. False means use hq output to correct SAM output. True means use hq output only. Default: False. | |
| To achieve best visualization effect, for images contain multiple objects (like typical coco images), we suggest to set hq_token_only=False. For images contain single object, we suggest to set hq_token_only = True. | |
