can we get geometrical dimensions from image input

Given an image input, can we extract height, length, breadth from the image

[Ameer Hamza]

Can you show an example of what information you are trying to extract from the image? Is there an object in the image, and you are trying to find its dimensions?

Hi,

Use the function size() with the image matrix as input and we get length, breadth, depth as outputs in terms of pixels.

To read the image you can use imread() function
