Cropping an image as a 3d array

I have a tensor of dimension (224, 224, 3) representing an image. I would like to firstly "crop" this image using bounding box dimensions in the format bndbox = [x1, y1, x2, y2] and then resize this cropped image back to a dimension of (224, 224, 3).

Is there a simple way of doing this with numpy/cv2(OpenCV)?

Supposing that your tensor supports slicing, simply select the bounding box, then you can resize with cv2.resize:

cv2.resize(img[y1:y2,x1:x2], (224, 224))

Just note that img is probably selected in height then in width, while the shape argument for cv2.resize takes (width, height).
