This page is a part of CVprimer.com, a wiki devoted to computer vision. It focuses on low level computer vision, digital image analysis, and applications. It is designed as an online textbook but the exposition is informal. It geared towards software developers, especially beginners, and CS students. The wiki contains mathematics, algorithms, code examples, source code, compiled software, and some discussion. If you have any questions or suggestions, please contact me directly.

# Algorithm for hexagonal and triangular cells

Create an article - Algorithm for hexagonal and triangular cells

# Analysis of hands

Should be clear...

# Are there inaccessible areas in the maze?

Consider 1-cycles. If there are more than one 1-cycle, the answer is yes. Run Pixcavator - for this particular image, there is only one 1-cycle...

# Can you get from A to B in the maze?

Consider 1-cycles. If A and B are inside the same 1-cycle, the answer is yes. For this particular image, there is only one 1-cycle...

# Compute DDP

Should be zero, always!

# Graph for Gridface

The pixels are added row by row, left to right. In the graph they are numbered according to their coordinates.

# Is the bone broken?

Consider 0-cycles. If there is no 0-cycle that connects top to bottom, the answer is Yes.
