Measuring character and stroke sizes and spacings for an image

摘要: A processor measures size or spacing of connected components for an image text by obtaining a distribution measurements distances between edges components. The are measured along lines extending in measuring direction, such as direction parallel perpendicular to text, which can be determined based on measurement skew. distance then used produce function distance, histogram. Sufficient that the histogram other data indicates measure image, stroke width, maximum character width height, characters, words, lines. To sizes, across pixels within spacings, not Measurements indicate intercharacter spacing, interword vertical and width. interline horizontal height. machine could store input memory, obtain indicating components, modify stored according sizes spacings indicated, provide output modification. segmentation recognition.
