Abstract

The invention discloses an evaluation method and system for writing neatness. The method comprises: a neatness evaluation model for writing neatness evaluation based on writing neatness features is constructed in advance; a to-be-evaluated writing image is obtained; grayscale maps of all writing regions in the to-be-evaluated writing image are obtained; writing neatness features are extracted from all grayscale maps; the writing neatness features are inputted into the neatness evaluation model to obtain a writing neatness score. According to the method disclosed by the invention, because the writing neatness features can reflect the writing neatness information and can be extracted automatically by a computer, the writing neatness score is obtained automatically; and the writing neatness sore is objective and fair.

Description

technical field [0001] The invention relates to the fields of image processing and educational informatization, in particular to an evaluation method and system for neatness of writing. Background technique [0002] With the development of computer science and technology, the ability and level of automatic information processing has also been significantly improved. The education model is also gradually developing in the direction of information automation. The emergence of the automatic marking system will liberate people from heavy mechanical labor. Machine marking is not only conducive to making an objective and fair evaluation of students' grades, but also the results of marking are easy to save, count and query. Machine grading is an inevitable trend in the age of intelligence, but there are also some shortcomings. For example, machine grading erases the factors of neatness in writing: writing with different degrees of cleanliness is uniformly transcribed into text for...
