SegIC: A Generalist Model for Segmenting Everything in Context

Model Overview

Description:

The SegIC (Segment-In-Context) model is designed for in-context segmentation, which aims to segment novel images using a few labeled example images (in-context examples). The research study is at SEGIC: Unleashing the Emergent Correspondence for In-Context Segmentation.

This model is ready for commercial use.

SegIC shows powerful performance as a generalist model for segmenting everything in context. It achieves SOTA results in COCO-20i, FSS-1000 and recent LVIS-92i. The NVIDIA SegIC model is ready for commerical use. It has a deployable version available. We also demonstrate its advantageous performance in retail object detection, while only training the model with a fair number of synthetic retail data.

Model Architecture:

Architecture Type: Vision Transformer
Network Architecture: SegIC is mainly built upon a vision foundation model, a text encoder, and a lightweight mask decoder

  • Image encoder: For image feature extraction. DINOv2-L traind with proprietary images from NVIDIA
  • Meta description encoder: For meta feature extraction. CLIP-B trained with proprietary images from NVIDIA
  • Mask Decoder: For mask decoding. It is mainly composed of a few convolutional layers, projection layers and a transformer decoder.

For more details, please refer to the research paper stated in References.

Input:

Input Types:

  • Example images: the example image containing target objects
  • Example image masks: the masks of target objects in the example images. Each mask only contains one object.
  • (Optional) Meta description: a sentence or words describing target objects
  • Target image: the test image in search of target objects
  • Original size: the original size of the target image

Input Formats:

  • Example images: Red, Green, Blue (RGB). Can support any input resolution and images do not need any additional pre-processing (e.g. alpha channels or bits), but all example images needs to be in the same size.
  • Example image masks: Grayscale. Resolutions needs to be the same as the example images.
  • (Optional) Meta description: Tokenized String. Max length 77 words.
  • Target images: Red, Green, Blue (RGB). Can support any input resolution and images do not need any additional pre-processing (e.g. alpha channels or bits).
  • Original size: Height, width

Input Parameters:

  • Example images: Four dimensional (4D), batch_size x 3 x896 x896
  • Example image masks: 4D, batch_size x 1 x896 x896
  • meta description: 2D, batch_size x 64
  • Target images: 2D, 1 x 3 x 896 x 896
  • Original sizes: 2D, 1 x 2

Other Properties Related to Input:

  • Example images: Resized to 896x896 at input
  • Example image masks: Resized to 896x896 at input
  • Target image: Resized to 896x896 at input. Currently it only supports one target image each time at inference.

Output:

Output Types: Predicted segmentation masks.
Output Format: a tensor with shape of batch_size x 1 x 896 x 896
Output Parameters: Four Dimensional
Other Properties Related to Output:

  • segmentation masks: resolution 896x896. Post-processing is needed to resize predicted masks to Target images original sizes.
    Post processing step:

    # original size: W x H, predicted mask size: 896 x 896
max_l = max(W, H)
h = 896 * H/max_l
w = 869 * W/max_l
pred_mask = pred_mask[:, :, :h, :w]
pred_mask_original_size = interpolate(pred_mask, (H, W))
