Caption-Anything is a versatile image processing tool that combines the capabilities of Segment Anything, Visual Captioning, and ChatGPT. Our solution generates descriptive captions for any object within an image, offering a range of language styles to accommodate diverse user preferences. It supports visual controls (mouse click) and language controls (length, sentiment, factuality, and language).
