چکیده

This paper presents an evaluation of eleven locally adaptive binarization methods for gray scale images with low contrast, variable background intensity and noise. Niblack’s method with the addition of the postprocessing step of Yanowitz and Bruckstein’s method added performed the best, and was also one of the fastest binarization methods. Keywords— Locally adaptive binarization, Thresholding, Evaluation, Utility maps, Document images.

Recognition of Digits in Hydrographic Maps: Binary Versus Topographic Analysis

This paper compares the performance of topographic analysis and binary analysis for recognition of digits in hydrographic maps. The performance of each method was measured by the correct classification rate of the final symbol recognition step when processing a complete hydrographic map of size 0.45× 0.6m with about 35,000 digits. The experimental results indicated that binary analysis had a be...

Recognition of Digits in Hydrographic Maps: Binary vs. Topographic Analysis

This paper compares the performance of topographic analysis and binary analysis for recognition of digits in hydrographic maps. Each of the methods processed the input image by extracting binary print components, recognizing long lines, splitting touching digits, and, finally, recognizing individual symbol candidates. The topographic analysis extracted the information by computing topographic l...
