Counting Teeth

06 Oct 2004 (Updated 08 Jun 2009)

Use some image processing algorithms to count the number of teeth on a gear.

File Information
Description	This file demonstrates how the Cell Execution Mode is useful in creating and publishing MATLAB script M-files. Starting with a picture of a clock gear, we work step by step to determine how many teeth are on the gear. See the related News and Notes article for more information.
Required Products	Image Processing Toolbox
MATLAB release	MATLAB 7.8 (R2009a)

11 Mar 2013	omid	Thanks Dr. Ned I could download it. I have a question: I am PhD student in mining engineering. Actually, for my thesis I want to measure drill bit wear by taking subsequent photos from drill bit after drilling and then use image processing to measure wear area of the bit. After e.g. a 100 m drilling I will take photo from bit surface and then compare with previous one. The problem is shortening the bit how can effect this in the analsys? Many thanks for attention
