直方图和直方图边界框

[英]Histogram,and histogram bounding box

原文 2014-04-29 11:33:34 4 1 python/ opencv/ image-processing

would i go about detecting this kind of Moth based on its Histogram.i followed tutorials and i do i need to calculate it first for the isolated moth and then find that specific histogram in the webcam feed ? 我会根据它的Histogram.i跟踪教程来检测这种蛾类吗？我是否需要先为孤立的蛾计算它，然后在网络摄像头中找到特定的直方图？ if so, how to search for specific Histogram values within that picture ? 如果是这样，如何在该图片中搜索特定的直方图值？ Also how to go about creating a bounding box around the target ? 另外如何在目标周围创建边界框？

What you need to do is: 你需要做的是：

1) Calculate the histogram of the "isolated moth" and store it. 1）计算“隔离蛾”的直方图并存储。

2) Do backprojection with your model histogram and the input image. 2）使用模型直方图和输入图像进行反投影。 The zones of the image containing the histogram you are looking for should "glow" in the backprojection image. 包含您要查找的直方图的图像区域应在反投影图像中“发光”。

3) If you want to generate rectangle-shaped regions with the location, use 2D moments . 3）如果要生成带有位置的矩形区域，请使用2D矩。
