Snakes with class

Implementation of snakes using a class to enable automatic display of the snake over an image.

Description

This package implements snakes (active contours) through a class `dip_snake`. The function `snakeminimize` modifies the snake to move it to a lower energy configuration, which typically corresponds to the snake following edges in an image. When the semicolon is left off a statement that returns an object of this class, the snake is automatically drawn on top of the image in the current figure window.

`snakeminimize` is very general in the sense that it can be used to implement many types of snakes found in the literature. The snake's external force is an input parameter, and hence the user can implement the GVF (gradient vector flow) or VFC (vector field convolution) external forces, or simply use the gradient. The balloon force is included.

This package add to and builds on DIPimage, a scientific image analysis toolbox for MATLAB. See http://www.diplib.org/

hi,
i'm having Matlab 7.8.0 R2009 in windows platform, could you please let me know, how to run this file?

Vivek,

It's explained in the README file inside the ZIP that you download here. You need to install DIPimage (from http://www.diplib.org/). Then copy the two M-files "snakeminimize.m" and "dip_snake.m" to the "dip/common/dipimage/" directory and the M-file "private/paramtype_snake.m" to "dip/common/dipimage/private/". You might need to CLEAR FUNCTIONS before you can use these functions.

Please let me know what it is that is not working!

Cris.
