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 20):
The non-transitory computer-readable medium having embodied thereon a computer program for executing a method comprising\n receiving a line and graphic eliminated image; performing horizontal projection on a plurality of rows of the line and graphic eliminated image to obtain a first flag vector for the plurality of rows, wherein the first flag vector indicates whether there is text in each of the plurality of rows; computing a number of run-lengths of consecutive 1's and 0's in the first flag vector; extracting a plurality of text lines in the line and graphic eliminated image based on the computed number of run-lengths of consecutive 1's and 0's in the first flag vector; performing vertical projection on a plurality of columns of each of the plurality of text lines to obtain a second flag vector for each of the plurality of text lines, wherein the second flag vector indicates whether there is text in each of the plurality of columns of each of the plurality of text lines; computing a number of run-lengths of consecutive 1's and 0's in the second flag vector of each of the plurality of text lines; and localizing text in the line and graphic eliminated image based on the computed number of run-lengths of consecutive 1's and 0's in the second flag vector of each of the plurality of text lines.
