Combining statistical measures to find image text regions
P. Clark, Majid Mirmehdi · 2002
We present a method based on statistical properties of local image pixels for focussing attention on regions of text in arbitrary scenes where the text plane is not necessarily fronto-parallel to the camera. This is particularly useful for desktop or wearable computing applications. The statistical measures are chosen to reveal characteristic properties of text. We combine a number of localised measures using a neural network to classify each pixel as text or non-text. We demonstrate our results on typical images.
