The problem of recovering an input signal from noisy and linearly distorted data arises in many different areas of scientific investigation; e.g., noisy Radon inversion (tomography) is a problem of sp...
Text Detection in Images Using Texture Feature from Strokes
text detection wavelet decomposition co-occurrence matrix
2006/12/31
Text embedded in images or videos is indispensable to understand multimedia information. In this paper we propose a new text detection method using the texture feature derived from text strokes. The m...
