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 7):
The method of  claim 1 , wherein extracting the 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, comprises:\n eliminating objects in the line and graphic eliminated image based on the run-lengths of  1 's in the first flag vector, wherein the objects comprise noise pixels; substantially simultaneously eliminating gaps in the line and graphic eliminated image based on the run-lengths of 0's in the first flag vector, wherein the gaps comprises letter gaps; identifying start and end positions of the plurality of text lines in the line and graphic eliminated image based on the run-lengths of 1's in the first flag vector upon eliminating the gaps and objects in the line and graphic eliminated image, wherein identifying the start and end positions of the plurality of text lines comprises steps of:\n separating areas in the line and graphic eliminated image where run lengths of 1's are greater than a first threshold; and \n identifying the separated areas as the start and end positions of the plurality of text lines; and \n extracting the plurality of text lines based on the start and end positions of the text lines.
