Performance optimization for applylut 2

I thought I would finish my discussion of applylut and makelut by describing a performance optimization we implemented for version 6 (R2007b) of the Image Processing Toolbox.
A couple of years ago,... read more >>

Lookup tables for binary image processing—Conway’s Game of Life 2

This is the third post about using lookup tables to process binary images. The first two posts were: Introduction Basic... read more >>

Lookup tables for binary image processing—makelut and applylut 9

This is the second in a short series on using lookup tables for binary image neighborhood operations. See the first post for the basic idea. The Image Processing Toolbox has two... read more >>

Anti-aliased text in color 4

Over the past few years I've been fascinated to see the progress in making text look better on the screen. (I should confess right away that I know nothing about typography, and almost nothing... read more >>

Lookup tables for binary image processing 2

Today I'm introducing a short series about using lookup tables to implement neighborhood operations in binary images. This is a fast implementation technique that works for small... read more >>

Visualizing the output of bwlabel 4

I often find myself writing small functions that help visualize certain image processing algorithms. For example, my last three posts on bwlabel included identical snippets of code that... read more >>

Corresponding labeled objects in two images 10

Several questions I've seen about bwlabel are about finding the correspondences between object labels in two images. In other words, if a particular pixel is in the foreground in two... read more >>

Relabeling a label matrix 16

The three most common questions I've been hearing about bwlabel, which is used for labeling connected components in a binary image, are about Search order ... read more >>
