Abstract:
System and method for text localization in images are disclosed. In an embodiment, a line and graphic eliminated image is received. Further, horizontal projection is performed on rows of the image to obtain a first flag vector, the flag vector indicates whether there is text in each row. Furthermore, a number of run-lengths of consecutive 1's and 0's is computed in the first flag vector. Moreover, text lines is extracted in the image based on the computed number of run-lengths of consecutive 1's and 0's in the first flag vector. Also, vertical projection is performed on the text lines to obtain a second flag vector for the text lines. Further, a number of run-lengths of consecutive 1's and 0's is computed in the second flag vectors. Furthermore, text is localized in the image based on the computed number of run-lengths of consecutive 1's and 0's in the second flag vectors.

Claim (Index 14):
The system of  claim 13 , wherein the one or more hardware processors are capable of executing programmed instructions to:\n detect lines in the image, wherein the lines comprise horizontal lines and vertical lines; identify line neighborhood along each of the detected lines; apply vertical projection on the identified line neighborhood along each of the detected lines; apply histogram on the vertically projected line neighborhood to obtain a width of the associated line; perform horizontal edge detection on the line neighborhood along each of the detected lines; remove the detected lines based on the horizontally detected edges and the width of the associated line; and apply dilation on the image upon removing the lines and performing logical AND operation with the associated line neighborhood to preserve one or more character strokes connected to the corresponding line.
