Segformer B3 Fashion

🚀 segformer-b3-fashion

segformer-b3-fashion 是一個圖像分割模型，它基於特定數據集進行微調，可對時尚相關的圖像進行分割，識別多種時尚物品和服飾細節，在時尚圖像分析等領域有重要應用價值。

🚀 快速開始

segformer-b3-fashion 模型是 nvidia/mit-b3 在 sayeed99/fashion_segmentation 數據集上的微調版本，微調過程使用原始圖像尺寸，未進行縮放。

以下是使用該模型進行圖像分割的示例代碼：

from transformers import SegformerImageProcessor, AutoModelForSemanticSegmentation
from PIL import Image
import requests
import matplotlib.pyplot as plt
import torch.nn as nn

processor = SegformerImageProcessor.from_pretrained("sayeed99/segformer-b3-fashion")
model = AutoModelForSemanticSegmentation.from_pretrained("sayeed99/segformer-b3-fashion")

url = "https://plus.unsplash.com/premium_photo-1673210886161-bfcc40f54d1f?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxzZWFyY2h8MXx8cGVyc29uJTIwc3RhbmRpbmd8ZW58MHx8MHx8&w=1000&q=80"

image = Image.open(requests.get(url, stream=True).raw)
inputs = processor(images=image, return_tensors="pt")

outputs = model(**inputs)
logits = outputs.logits.cpu()

upsampled_logits = nn.functional.interpolate(
    logits,
    size=image.size[::-1],
    mode="bilinear",
    align_corners=False,
)

pred_seg = upsampled_logits.argmax(dim=1)[0]
plt.imshow(pred_seg)

image = Image.open(requests.get(url, stream=True).raw)
inputs = processor(images=image, return_tensors="pt")

outputs = model(**inputs)
logits = outputs.logits.cpu()

upsampled_logits = nn.functional.interpolate(
    logits,
    size=image.size[::-1],
    mode="bilinear",
    align_corners=False,
)

pred_seg = upsampled_logits.argmax(dim=1)[0]
plt.imshow(pred_seg)
