Here's how to use it: 1. **Select Task Type**: Choose the type of task you want to perform from the "Task Type" dropdown menu. 2. **Upload Images**: Drag and drop images directly onto the upload area, or click to select files from your device. 3. **Generate Captions**: **If you upload any images**, Click the "Generate Captions" button to format the text prompt according to chosen task. In this demo, you will **NEED** to provide the caption of each source image manually. We recommend using Molmo for captioning. 4. **Configure Generation Settings**: Expand the "Advanced Configuration" section to adjust parameters like the number of inference steps, guidance scale, image size, and more. 5. **Generate Images**: After setting your preferences, click the "Generate Image" button. The generated images will appear in the "Generated Images" gallery. 6. **Manage Images**: Use the "Delete Selected Images" or "Delete All Images" buttons to remove unwanted images from the gallery. **Notes**: - Check out the [Prompt Guide](https://github.com/lehduong/OneDiffusion/blob/main/PROMPT_GUIDE.md). - For text-to-image: + simply enter your prompt in this format "[[text2image]] your/prompt/here" and press the "Generate Image" button. - For boundingbox2image/semantic2image/inpainting etc tasks: + To perform condition-to-image such as semantic map to image, follow above steps + For image-to-condition e.g., image to depth, change the denoise_mask checkbox before generating images. You must UNCHECK image_0 box and CHECK image_1 box. Caption is not required for this task. - For FaceID tasks: + Use 3 or 4 images if single input image does not give satisfactory results. + All images will be resized and center cropped to the input height and width. You should choose height and width so that faces in input images won't be cropped. + Model works best with close-up portrait (input and output) images. + If the model does not conform your text prompt, try using shorter caption for source image(s). + If you have non-human subjects and does not get satisfactory results, try "copying" part of caption of source images where it describes the properties of the subject e.g., a monster with red eyes, sharp teeth, etc. - For Multiview generation: + The input camera elevation/azimuth ALWAYS starts with 0. If you want to generate images of azimuths 30,60,90 and elevations of 10,20,30 (wrt input image), the correct input azimuth is: `0, 30, 60, 90`; input elevation is `0,10,20,30`. The camera distance will be `1.5,1.5,1.5,1.5` + Only support square images (ideally in 512x512 resolution). + Ensure the number of elevations, azimuths, and distances are equal. + The model generally works well for 2-5 views (include both input and generated images). Since the model is trained with 3 views on 512x512 resolution, you might try scale_factor of [1.1; 1.5] and scale_watershed of [100; 400] for better extrapolation. + For better results: 1) try increasing num_inference_steps to 75-100. 2) avoid aggressively changes in target camera poses, for example to generate novel views at azimuth of 180, (simultaneously) generate 4 views with azimuth of 45, 90, 135, 180.
