Deep Learning CNN Convolutional Neural Networks with Python - Shift Scale Rotation Invariance Exercise

This video tutorial covers a simple object detection process using thresholding without deep learning. It involves reading an image, converting it to grayscale, applying thresholding, and detecting contours. The tutorial also addresses common errors and demonstrates how to draw contours and display results using plots.
