Segformer B4 Finetuned Ade 512 512

🚀 SegFormer (b4-sized) model fine-tuned on ADE20k

A SegFormer model fine-tuned on ADE20k at 512x512 resolution, designed for efficient semantic segmentation.

🚀 Quick Start

The SegFormer model presented here is fine-tuned on the ADE20k dataset at a resolution of 512x512. It was first introduced in the paper SegFormer: Simple and Efficient Design for Semantic Segmentation with Transformers by Xie et al. and initially released in this repository.

Disclaimer: The team that released SegFormer did not create a model card for this model. This model card was written by the Hugging Face team.

✨ Features

SegFormer combines a hierarchical Transformer encoder with a lightweight all - MLP decode head, achieving excellent results on semantic segmentation benchmarks like ADE20K and Cityscapes. The hierarchical Transformer is pre - trained on ImageNet - 1k, and then a decode head is added and fine - tuned on a downstream dataset.

💻 Usage Examples

Basic Usage

Here is an example of using this model to classify an image from the COCO 2017 dataset into one of the 1,000 ImageNet classes:

from transformers import SegformerFeatureExtractor, SegformerForSemanticSegmentation
from PIL import Image
import requests

feature_extractor = SegformerFeatureExtractor.from_pretrained("nvidia/segformer-b4-finetuned-ade-512-512")
model = SegformerForSemanticSegmentation.from_pretrained("nvidia/segformer-b4-finetuned-ade-512-512")

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)

inputs = feature_extractor(images=image, return_tensors="pt")
outputs = model(**inputs)
logits = outputs.logits  # shape (batch_size, num_labels, height/4, width/4)
