Lesson 9 - Non-Linear Operations

This lesson demonstrates non-linear operations using VisiQuest:

Edge Detection I | Edge Detection II | Median Filtering | Dilation | Contours

Each section takes you through an incremental portion of the lesson while building on skills learned in previous lessons and sections.

Section 1 - Edge Detection I

Detect edges using the Sobel gradient operator.

Section 2 - Edge Detection II

Detect edges using Roberts, Sobel, Prewitt and Isotropic gradients.

Section 3 - Median Filtering

Remove noise from image data while maintaining detail and without loosing small details.

Section 4 - Dilation

Use Morphology operations dilation, erosion, opening, and closing.
