Lesson 3 - Point Operations (Dual Operands)
This lesson demonstrates point operations using VisiQuest:
Patterns | Image Combining | Image Overlaying I | Image Overlaying II | Mask Application | Color Image Composing | Dithering
Each section takes you through an incremental portion of the lesson while building on skills learned in previous lessons and sections.
Synthetic images and patterns can be used as test patterns to calibrate equipment, to generate convolution kernels, filter masks, and to generate blending functions.
Blend two images with an averaging function and a combination function.
Section 3 - Image Overlaying I
Overlay a line-grid on top of an image.
Section 4 - Image Overlaying II
Overlay a binary annotation image over a grey-level image where a simple Maximum and Minimum are not appropriate.
Use a mask or "validity mask" segment within an image file to inform which pixels in an image are valid.
Section 6 - Color Image Composing
Use a pointwise operation to perform the multiplication of two RGB Images.
Display a grey-level image in a bilevel device such as monochrome displays and printers.
