Matlab图像中对象的边界框 [英] Bounding box of an object in an image Matlab

问题描述

我想获取图像中对象的边界框位置(x，y，宽度和高度)并将其保存到文本文件中.如下图所示.所以，如果有人可以请指教. 可以在此处找到该图像

I want to get the object's bounding box positions (x, y, width and height) in the image and save it to a text file. As shown in the below image. So if anyone could please advise. The image can be found here

推荐答案

假设您已使用imread读取了图像，则此方法应该有效:

Assuming you have read the image using imread, this should work:

bwImage=~im2bw(img,0.98);  %making gray pixels white and (almost) white pixels black
bndBox=regionprops(bwImage,'BoundingBox');

bndBox的边界框的左上角，其宽度和高度以[corner_x corner_y width height]格式存储.

bndBox will have top-left corner of the bounding box and its width and height stored in the format [corner_x corner_y width height].
