pixellib庫的簡介

? ? ? ? pixellib是一個庫執行圖像分割。它支持兩種主要類型的圖像分割:語義分割和實例分割，只需幾行代碼就可以實現語義分段和實例分段。特的特點如下：

• 高質量反色矢量/光柵圖形
• 多像素格式:RGB, BGR, ARGB, ABGR, RGBA, BGRA 8 / 15 / 16 / 24 / 32深度
• 重量輕100% C實現
• MMX / SSE2圖形優化

pixellib庫的經典案例

1、使用pixellib進行語義分割

pixellib使用Deeplabv3+框架實現，實現語義分割。采用在pascalvoc上預訓練的Xception模型進行語義切分。基于xception模型的語義分割在pascalvoc上進行預處理。

• 用于執行語義分段的類是從pixellib導入的，我們創建了該類的一個實例。
• 我們調用函數來加載在pascal voc上訓練的xception模型?？梢詮倪@里下載xception模型。
• 這是對圖像執行分割的代碼行，分割是在pascalvoc的顏色格式中完成的。這個函數有兩個參數:? ?
  path_to_image:要設置的映像的路徑。?
  path_to_output_image:保存輸出圖像的路徑。映像將保存在當前工作目錄中。

import pixellib from pixellib.semantic import semantic_segmentationsegment_image = semantic_segmentation() segment_image.load_pascalvoc_model("deeplabv3_xception_tf_dim_ordering_tf_kernels.h5") segment_image.segmentAsPascalvoc("path_to_image", output_image_name = "path_to_output_image")
