Face to Sticker

Face to sticker model takes an image of a person and creates a sticker image. This is based on style transfer, where essentially the sticker style is created for an input image of a person. The output is a new image that looks like a sticker but retains the facial features of the person in the input image. This model helps in the creation of personalized stickers from just about any image of a person.

Key Components of Face to Sticker

Under the hood of Face to sticker model is a combination of Instant ID + IP Adapter + ControlNet Depth + Background removal.

1. •

   Instant ID is responsible for identifying the unique features of the face of the person in the input image.

2. •

   An image encoder (IP Adapter) helps in transferring the sticker style on to the face image of the person in the input image.

3. •

   ControlNet Depth estimates the depth of different parts of the face. This helps in creating a 3D representation of the face, which can then be used to apply the sticker style in a way that looks natural and realistic.

4. •

   Background Removal removes the background, resulting in a clean sticker image.

How to use Face to Sticker

1. •

   Input image: Choose an image that you want to transform into a sticker. A close-up portrait shot is ideal because it allows the model to clearly identify and process the facial features.

2. •

   Prompt: Provide a text prompt based on the input image. This could be a simple description of the person in the image, such as “a man” etc. The model uses this prompt to guide the style transfer process.

3. •

   Parameters: Adjust the below parameters to guide the final image output.

     a. Prompt Strength: This parameter is similar to the CGF scale. It determines how closely the image generation follows the text prompt. A higher value will result in an output image that more closely matches the prompt.
   
     b. IP Adapter Noise:  This parameter determines the degree of influence of the sticker style. A higher value will result in a more stylized output image
   
     c. IP Adapter Strength: This parameter determines the weight of influence of the sticker style. A higher value will result in a stronger application of the sticker style to the output image.
   
    d. Instant ID strength: This parameter determines how closely the output image resembles the person in the input image. A higher value will result in an output image that more closely resembles the input image.
