这四个值分别表示图形坐标系统的[bottom,left,width,height](底坐标、左坐 标、宽度、高度),数值的取值范围是左下角(原点)为 0,右上角为 1。 如果想要在右上角创建一个画中画,那么可以首先将x与y设置为 0.65(就是坐标轴原点 位于图形高度 65% 和宽度 65% 的位置),然后将x与y扩展到 0.2(也就是将坐标...

如果形状为 (height, width, 3),则表示图像具有RGB通道。 代码语言:txt 复制 if image.shape[2] == 3: rgb_image = image else: # 如果图像具有其他通道(如RGBA),则可以通过切片操作提取RGB通道 rgb_image = image[:, :, :3] 现在,rgb_image变量将包含图像的RGB通道。您可以对其进行进一步处理或可视化...
