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.
Detect edges using the Sobel gradient operator.
Detect edges using Roberts, Sobel, Prewitt and Isotropic gradients.
Remove noise from image data while maintaining detail and without loosing small details.
Use Morphology operations dilation, erosion, opening, and closing.
Differentiate between a dilated image and the original to create a contour.
