To detect text information from image, there exist many practical difficulties, such as non-uniform backgrounds, due to the large variations in character font, size, texture, color, background, orientations, and many other reasons. Text detection from scene/text camera images is possible due to high resolution camera. For extracting text information from image, algorithms are required. To solve these difficult problems captured image text is divided into two processes: text detection and text recognition. Text detection is used to detect image region containing text characters. Text recognition is to convert pixel based text into readable code. Optical character recognition is the electronic conversion of images captured by a digital camera of printed text into readable text.
