MultiCrops在同一图像中 [英] MultiCrops in same image

问题描述

我有一张图像里面有6张图片..我的任务是从这张图片中裁剪掉6张图片..

I ve an image which has 6 images within it..I ve the task of cropping the 6 images out of this image..

目前我按照这个程序..

1.保存原始图像的副本

2.使用任何工具（Picasa）裁剪图像以获取第一张图像

3.保存裁剪图像为图像1

4.打开原稿以裁剪图像2

5.重复此次6次

Currently I follow this procedure..
1. Save copy of original image
2. Crop the image to get first image using any tool(Picasa)
3. Save the cropped image as image 1
4. Open the original to crop for image 2
5. Repeat this 6 times

是有一种方法可以一次性提取所有6张图像吗？多重裁剪？

Is there a way in which I can extract out all the 6 images in one go? Multi-cropping?

推荐答案

是的，这是可能的。您需要熟悉投资回报率（感兴趣的区域）概念。

Yes, it's possible. You need to get familiarized with the ROI (Region of Interest) concept.

此 C 示例显示了如何在图像中设置ROI。基本上，它在相机的帧中设置ROI，从中创建新图像，在图像中进行一些处理（反转颜色），然后将图像复制回原始帧以供显示。

This C example shows how to set a ROI in an image. Basically it sets a ROI in a frame from the camera, creates a new image from it, does some processing (invert colors) in the image and then copies the image back to the original frame for display.

此 Python 示例还说明了如何使用投资回报率。

This Python example also shows how to work with ROIs.
