image and pattern classification using neural networks

2 New Member
i would like to build a software coding which can classify image and pattern using artificial neural networks

the idea is it should be able to do feature extraction on a certain image (can consist of characters/pictures) and let the network learn about the difference of each extracted image and finally able to decide what the image is and classify it.

is there any code for the feature extraction part?? or any coding or ideas on how to perform this project??
i've currently done some part of the neural network training code (classify characters A-Z) in matlab environment.

anyone can help with this??
your response is really appreciated

thanks alot

Hi, Can anyone please recommend a python-accessible library for neural network simulation? I've already got code for standard feed-forward, back-propagation networks, but am needing something which does recurrent networks. Also desirable is self-organising maps and Hopfield nets.

Hi all, I am still new to using Python, so bare with me. I am trying to call a DLL from my program to use some of it's functions. The only parameter is supposed to be a pointer to an image. I have tried several variations on passing this parameter to the DLL and I am not having much luck. This is going to call other functions later for OCR, but I want to get a simple one working first. Here is my code: (Very basic)

Hi all, I'm looking for a C++ (or at least C) library that implements both standard feedforward neural networks and also recurrent neural networks (RNN)... Any suggestion? I tried FANN but it doesn't have any RNN support, ANNIE seems hard to compile and however RNN support seems to be limited. Thanks in advance for any help! Andrea

A friend of mine just was over at my house explaining Neural Networks and I understood it as well as I could. Here is my own explination. A neural network has to first run in a loop 1,000's of times given it's input and output. It then naturally learns the simplest algorithm to generate that input and output, using a networked matrix of numbers that are run through a filter, and compared to the input. The algorithm to train a neural...

Hi all, What frameworks are there available for doing pattern classification? I'm generally interested in the problem of mapping some sort of input to one or more categories. For example, I want to be able to solve problems like taking text and applying one or more tags to it like "romance", "horror", "poetry", etc. This isn't really my research specialty, but my understanding is that Bayesian classifiers are generally used for problems...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

For most users, this new feature is actually very convenient. If you want to control the update process,...
