In order to solve the problem of poor grammar error detection effect in English text images, a grammar error detection method in English text images based on sparse representation is proposed. The characteristic data of English text images are collected, and the English text image evaluation system is constructed. Combined with the principle design of sparse representation and the grammar error recognition algorithm, it is verified by experiments, the grammar error detection method in English text images based on sparse representation has high practicability and fully meets the research requirements.
