Crop
Cropping is an image-processing operation that removes portions of an image to retain a selected subregion.

A crop tool is an image-editing control for selecting and retaining part of an image while removing content outside the selection.
- How it is used
- Improves image composition by reframing scenes, strengthening focal points, and avoiding rigid symmetry.
- How deep it goes
- Defines cropping, explains rule-of-thirds rationale, and gives handle-dragging steps with iterative examples.
- Examples
- Uses cranes, a farmhouse landscape, and farmer portraits to compare focal-point placement and crop choices.
- What you can do after
- Apply it with a crop tool to position focal points, test aspect ratios, and select a balanced result.

Inside Deep Learning: Math, Algorithms, Models
A preprocessing operation that extracts a spatial subregion from an image, here used to create training and test variants for shift analysis.
- How it is used
- Uses cropping to diversify training inputs, stabilize testing, and measure CNN sensitivity to spatial shifts.
- How deep it goes
- Explains crop size, random versus center policies, dataset wiring, and offset evaluation, but defers cropping internals.
- Examples
- Demonstrates 24 × 24 crops from 32 × 32 CIFAR-10 images and an 8 × 8 grid of shifted predictions.
- What you can do after
- Apply cropping via PyTorch transforms and diagnose shift sensitivity by comparing predictions across manually extracted windows.
