This paper is to achieve a better efficiency in face recognition using Block Truncation Coding (BTC) using RGB and YCbCr colour space. Multilevel Block Truncation Coding is applied to image in RGB and YCbCr colour space up to four levels for face recognition. The experimental analysis has shown an improved result for Block Truncation Coding at Level 4 (BTC-level 4) as compared to other BTC levels of RGB colour space. Results displaying a similar pattern are realized when the YCbCr colour space is used. In addition, an improved result on all four levels is observed for YCbCr colour space.
