Crop frames in video and apply it on other frames.

Hello,

I have a video, which I split in frames. Now, I would like to take the first frame, crop it, and this crop apply on other frames. How I can do it?

Or is there any way to crop whole video?

As per question you have already done video to frame splits let's consider im1 and im2 have same size images, rxcx3 unit 8 type.

You can place any part of the image to another image of the same type. Let's say you want to crop the first images from the index 20 to 300 rows and 20 to 300 columns in all channels and put it the same as the second image.

im2(20:300,20:300,:)=im1(20:300,20:300,:);

#It's all about replace the data elements (applicable in all arrays), ensure that data type must be same.

Hope it helps!

Well, I dont know the parametres, so first I need to crop it by my hand and then save the crop area and use it to another frames.

So I want to crop something in right corner, so I would like to do it by hand, but now, I need the program remember the area and automatically crop that area in other frames

Yes, use imtool funtion to open the image and crop it as per the requirements and save the modified in current workspace

imtool(im1);
