| File Information |
| Description |
canny edge detection comprising of gaussian convolution,sobel operation.entire code is free of any in built matlab function except for image reading.threshold must be changed depending on the image and the feature to be extracted.
Do check out the updated gaussian convolution file , its more accurate than the previous one
Please note that the code execution time is low.This is because no inbuilt functions are used.
In order to improve up on speed please substitute the convolution code with the inbuilt function "conv2" |
| MATLAB release |
MATLAB 5.2 (R10)
|
| Other requirements |
preferrably pentium 4 processor |

category need to be changed.it more faster code |

There was a review indicating code was not fast.Just want to clear up the misconception. |

Updating gaussian smoothing , correcting few errors ,the code is written in vc++, no inbuilt functions are used , result equivalent to gaussian smoothing in opencv and matlab where a 3*3 kernel is used for smoothing |
