Abstract Text recognition in scene image and video frames is difficult because of low resolution, blur, background noise, etc. [...] Key Method We propose a line based date spotting approach using hidden Markov model (HMM) which is used to detect the date information in a given text. Different date models are searched from a line without segmenting characters or words. Given a text line image in RGB, we apply an efficient gray image conversion to enhance the text information. Wavelet decomposition and gradient…Expand
