Transliteration of Hiragana and Katakana Handwritten Characters Using CNN-SVM

Hiragana and katakana handwritten characters are often used when writing words in Japanese. Japanese itself is often used by native Japanese as well as people learning Japanese around the world. Hiragana and katakana characters themselves are difficult to learn because many characters are similar to one another. In this study, hiragana and basic katakana, dakuten, handakuten, and youon were used, which were taken from the respondents using a questionnaire. This study used the CNN method which will be compared with a combination of the CNN and SVM methods which have been designed to identify each character that has been prepared. Preprocessing of character images uses the methods of image resizing, grayscaling, binarization, dilation, and erosion. The preprocessed results will be input for CNN as a feature extraction tool and SVM as a tool for character recognition. The results of this study obtained accuracy with the following parameters: 69×69 image size, 3 patience values, val_loss monitor callbacks, Nadam optimization function, 0.001 learning rate value, 30 epochs value, and SVM RBF kernel. If using a system that only uses the CNN network, the accuracy is 87.82%. The results obtained when using a combination of CNN and SVM were 88.21%

Car license number recognition by a computer is a valuable work is highly motorized society. Japanese car license number plate containts four kinds of characters, KANJI, small numeral, HIRAGANA, and large numerals. Most former researches don\u27t have dealt with the KANJI recognition. In this paper, a new method for car license number recognition containing KANJI is proposed. Devised Hough transform is used for a plate extraction in a car image, and location features of each character on the plate are used for character segmentation. As the experimental results using 160 samples, 87.5% of whole character recognition rate can be obtained

Kanji Acquisition Techniques for L1 and L2 Japanese Studies

Kanji are ideograms, a morphographic system borrowed from the Chinese language and used in Japanese writing. 2,136 kanji are used in the average Japanese newspaper, required for academic certification and for expat job placement. A qualitative study was conducted to observe the optimum methods to learn and acquire kanji. Japanese native speakers who were educated by the Japanese school system grades 1 through 12 are classified as L1 or first language speakers. American students, L2 or second language speakers, must have been educated in the American education system grades 1-12. L1 speakers were students attending Central Washington University (CWU) study abroad programs and L2 students were Japanese Major or Minor degree seeking CWU students. A comparison between L1 and L2 speakers was observed by interviewing 10 students from each group on acquisition strategies. Both groups of participants were asked what methods and techniques aided them in passing standardized tests for Japanese kanji. Students described drilling repetition of kanji ideograms for memorization combined with reading for real time comprehension as the best method for kanji retention. Current study results show that frequent reading of Japanese kanji and understanding of the semantic and phonetic radicals that makeup each ideogram are the best ways to strategically acquire kanji
