Description

This demo shows some examples for image pre-processing before the recognition stage. the first example is just some commnads of image processing which are commonly used for preprocessing, while the second example shows how to use the simple command to automate the image processing stage especially in generating training dataset for neural network for recognition purpose. More information ca be found at:

(recognition stage will be uploaded in next example)

Dear Tom G,
Thanks for your comment. I really dunno how to reply you since you're not leaving any email or contact. this program is written in ML 7, and might gives some error on ML 6.5 and below. refer to comments on I&II and III for more infor on this.

Dear Fabricio Nunes ,
I've replied you question, do check your mail and see whether it helps.... thanks

??? In an assignment A(:,matrix) = B, the number of elements in the subscript of A and the number
of columns in B must be the same.

Error in ==> D:\fabricioC\fabricio\visao\fonte\simplecharrec(III)\edu_imgpreprocess.m
On line 26 ==> Ic(:,4) = 1:50;

Error in ==> D:\fabricioC\fabricio\visao\fonte\simplecharrec(III)\char3.m
On line 8 ==> img = edu_imgpreprocess(I);
