How do I extract ROI from an image?

Using OpenCV for efficiently extracting ROI from images

1. Convert the RGB image to gray-scale using “cvtColor()”
2. Remove noise from the gray-scale image by applying a blurring function “GaussianBlur()”
3. Finally applying the “Canny()” function to the blurred image to obtain the edges.

What is ROI OpenCV?

In this tutorial, we will learn how to select a bounding box or a rectangular region of interest (ROI) in an image in OpenCV. You would think that selectROI would be part of highgui that has functions for displaying images, drawing on images etc. However, selectROI is part of the tracking API!

How to crop an object in an image in Python?

Then we have this: So the images are cropped from the largest size to the smallest size. Notice how all the images are cropped rectangular, so that the first image has no white space, but the others do. This is the basic way to crop an object (or contour) in an image in Python using OpenCV.

How to crop an image using pillow library?

To crop an image we make use of crop () method on image objects. Returns : An Image object which represents the cropped image.

How do you crop an object in OpenCV?

OpenCV is very dynamic in which we can first find all the objects (or contours) in an image using the cv2.findContours () function. We can then do unique things such as crop out an object in the image. Now, there’s no crop () function in OpenCV, so we use some indexing methods to crop out an image using values we gain from the image from OpenCV.

Why are all cropped images rectangular in shape?

Each cropped image is rectangular in nature, because we crop purely by the width and height. There is no way using this method we can crop in any other way such as in a round fashion or elliptical fashion. Therefore, all cropped images will be rectangular.
