| Abstract: To address the challenge of extracting features for Chinese characters in complex scenarios, this paper proposes a Chinese character recognition solution based on multidimensional feature representation. Firstly, a key stroke feature extraction method integrating spatial information is introduced, capable of uniquely identifying Chinese characters using a small number of key features. Secondly, multidimensional features are extracted through a multitask network to enhance feature extraction capability and improve the accuracy of Chinese character recognition. Lastly, a character similarity algorithm is applied to eliminate noise and optimize recognition results. Experimental results show that compared to the PRAB (Pluggable Radical-Aware Branch) model, the proposed solution achieves performance improvements of 1.62 percentage points, 1.09 percentage points, 0.15 percentage points, and 1.27 percentage points in scene, web page, document, and handwritten datasets, respectively, demonstrating the effectiveness of the proposed solution. |
