[0047] Example 1
[0048] Step 1: Enter a think of the size of H × W. Wherein h is the number of image I longitudinal to each column, W is the number of image I horizontally.
[0049] Step 2: Enter the image I input to the text extraction model in step 1, and output the information of each text box t from the output layer of the CRNN neural network after the characteristic of the text information from the CTPN. t . This array contains {t x , T y , T w , T h , T a , Text, Confidence}, where: T x , T y Is the coordinate of the center of this text, T w , T h Is the width and high of this text, T a It is the inclination of the text box. Text is the textual content of the text box. Confidence is the confidence of this text box, and the value of the default confidence is above 0.95 is trusted.
[0050] Step 3: Remove the text box portion in the image I, fill the patch of kernel = (2, 2) with the background color block of the text box.
[0051] Step 4: In the semantic segmentation networ...
