Abstract
The phase-only filter (POF) to the classical matched filter is compared for the criteria of discrimination, correlation peak, and optical efficiency in Korean alphabet. In addition, logarithmically scaled POF is presented to improve the recognition efficiency and this shows the superior performances in English alpanumeric characters to Korean.
