Study on Tilt Correction Algorithm for the Workpiece Coding Character Image
Liang Chen · IEEE Software · 2012
In the area of pattern recognition,a tilt correction algorithm for artificial coding character image which is been preprocessed before recognition is researched and presented in this paper.Because of artificial coding,tilting character is unavoidable.And due to the complicated workpiece background and uneven lighting,the processing and tilt correction for character image become much more difficult.Combining with practical application in this paper,tilt correction for single character is done after image pre-processing and character segmentation of character image.The experiment shows that the algorithm is effective,and creates a favorable condition for the subsequent character recognition.
