A method and device for region identification are provided in the disclosure. The method includes: binarizing (201) a word region, to obtain the binarized word region, wherein the word region includes several words belonging to a same row; calculating (202) a histogram in a vertical direction for the binarized word region, wherein the histogram includes abscissas of pixels in each column and an accumulated value of foreground color pixels of the pixels in each column; and identifying (203) a character region of each of the words in the word region, according to distribution information of accumulated values in the histogram. The disclosure may solve the fact that, in related arts, the accuracy of character region location is relatively low and may obtains an effect that the character region of each word may be accurately located according to the distribution information of accumulated values of foreground color pixels in the histogram.
