🏃 Fast Segment Anything 🤗
" description = """This is a demo on Github project 🏃 [Fast Segment Anything Model](https://github.com/CASIA-IVA-Lab/FastSAM). 🎯 Upload an Image, segment it with Fast Segment Anything (Everything mode). The other modes will come soon. ⌛️ It takes about 4~ seconds to generate segment results. The concurrency_count of queue is 1, please wait for a moment when it is crowded. 🚀 To get faster results, you can use a smaller input size and leave high_visual_quality unchecked. 📣 You can also obtain the segmentation results of any Image through this Colab: [![Open in Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1oX14f6IneGGw612WgVlAiy91UHwFAvr9?usp=sharing) 😚 A huge thanks goes out to the @HuggingFace Team for supporting us with GPU grant. 🏠 Check out our [Model Card 🏃](https://huggingface.co/An-619/FastSAM) """ examples = [["assets/sa_192.jpg"], ["assets/sa_414.jpg"], ["assets/sa_561.jpg"], ["assets/sa_862.jpg"], ["assets/sa_1309.jpg"], ["assets/sa_8776.jpg"], ["assets/sa_10039.jpg"], ["assets/sa_11025.jpg"]] default_example = examples[5] css = "h1 { text-align: center } .about { text-align: justify; padding-left: 10%; padding-right: 10%; }" def fast_process(annotations, image, high_quality, device, scale): if isinstance(annotations[0],dict): annotations = [annotation['segmentation'] for annotation in annotations] original_h = image.height original_w = image.width if high_quality == True: if isinstance(annotations[0],torch.Tensor): annotations = np.array(annotations.cpu()) for i, mask in enumerate(annotations): mask = cv2.morphologyEx(mask.astype(np.uint8), cv2.MORPH_CLOSE, np.ones((3, 3), np.uint8)) annotations[i] = cv2.morphologyEx(mask.astype(np.uint8), cv2.MORPH_OPEN, np.ones((8, 8), np.uint8)) if device == 'cpu': annotations = np.array(annotations) inner_mask = fast_show_mask(annotations, plt.gca(), bbox=None, points=None, pointlabel=None, retinamask=True, target_height=original_h, target_width=original_w) else: if isinstance(annotations[0],np.ndarray): annotations = torch.from_numpy(annotations) inner_mask = fast_show_mask_gpu(annotations, plt.gca(), bbox=None, points=None, pointlabel=None) if isinstance(annotations, torch.Tensor): annotations = annotations.cpu().numpy() if high_quality: contour_all = [] temp = np.zeros((original_h, original_w,1)) for i, mask in enumerate(annotations): if type(mask) == dict: mask = mask['segmentation'] annotation = mask.astype(np.uint8) contours, _ = cv2.findContours(annotation, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE) for contour in contours: contour_all.append(contour) cv2.drawContours(temp, contour_all, -1, (255, 255, 255), 2 // scale) color = np.array([0 / 255, 0 / 255, 255 / 255, 0.9]) contour_mask = temp / 255 * color.reshape(1, 1, -1) image = image.convert('RGBA') overlay_inner = Image.fromarray((inner_mask * 255).astype(np.uint8), 'RGBA') image.paste(overlay_inner, (0, 0), overlay_inner) if high_quality: overlay_contour = Image.fromarray((contour_mask * 255).astype(np.uint8), 'RGBA') image.paste(overlay_contour, (0, 0), overlay_contour) return image # CPU post process def fast_show_mask(annotation, ax, bbox=None, points=None, pointlabel=None, retinamask=True, target_height=960, target_width=960): msak_sum = annotation.shape[0] height = annotation.shape[1] weight = annotation.shape[2] # 将annotation 按照面积 排序 areas = np.sum(annotation, axis=(1, 2)) sorted_indices = np.argsort(areas)[::1] annotation = annotation[sorted_indices] index = (annotation != 0).argmax(axis=0) color = np.random.random((msak_sum,1,1,3)) transparency = np.ones((msak_sum,1,1,1)) * 0.6 visual = np.concatenate([color,transparency],axis=-1) mask_image = np.expand_dims(annotation,-1) * visual mask = np.zeros((height,weight,4)) h_indices, w_indices = np.meshgrid(np.arange(height), np.arange(weight), indexing='ij') indices = (index[h_indices, w_indices], h_indices, w_indices, slice(None)) # 使用向量化索引更新show的值 mask[h_indices, w_indices, :] = mask_image[indices] if bbox is not None: x1, y1, x2, y2 = bbox ax.add_patch(plt.Rectangle((x1, y1), x2 -
