Model Pipeline - Drawing on images (lines, rectangles, circles, text)
This pipeline shows how an image is taken and simple shapes and text are drawn on it. This helps in highlighting parts of the image or adding information visually.

Data Flow - 5 Stages
1Input Image
1 image x 400 pixels height x 600 pixels width x 3 color channels→Load a color image from disk→1 image x 400 x 600 x 3
A photo of a park with trees and sky
↓
2Draw Line
1 image x 400 x 600 x 3→Draw a blue line from point (50,50) to (550,50)→1 image x 400 x 600 x 3
Image now has a blue horizontal line near the top
↓
3Draw Rectangle
1 image x 400 x 600 x 3→Draw a green rectangle from (100,100) to (300,200)→1 image x 400 x 600 x 3
Image now has a green rectangle around a tree
↓
4Draw Circle
1 image x 400 x 600 x 3→Draw a red circle centered at (400,300) with radius 50→1 image x 400 x 600 x 3
Image now has a red circle highlighting a flower
↓
5Draw Text
1 image x 400 x 600 x 3→Write white text 'Park View' at position (200,350)→1 image x 400 x 600 x 3
Image now shows the label 'Park View' near the bottom

Key Insight
Drawing on images changes pixel colors but does not alter image size or require training. It is a direct image editing step useful for highlighting or labeling parts of images.
