解码图片中的文本或任何简单对象

Question

I'm currently working on a personal project for decoding a text or any object in an image.

I'm using GD library for processing image. I have access to every pixel of image and its rgb color.

My question is not about coding,I'm just looking for an algorithm to decode image,or any advise for how to do that and I don't want to use any API, I want to do it by myself. I know that php has a face detection library, but it only recognizes faces in image, and I don't know how it does that .

for start, I assume that the object is white and the background is black (or any separate colors) .

summary : How can I define an object or a word for a php program and train it to recognize it from a picture?
