The ATD color human vision model is proposed to be the interpretation of human’s cone mechanisms. Therefore, it is more suitable for human eye’s vision. Besides, we also use the minimum average correlation energy approach to yield sharp correlation peak and achieve the distortion invariance. To compare the recognition ability between ATD vector model and RGB color model, we compare the PSR value for fifteen targets with different colors and shapes. Subsequently, we choose one target from the fifteen images set to estimate the discrimination ability in rotated distortion, noisy distortion, and multiple target recognition. From the numerical results we realize that the recognition ability based on ATD color vision model is accepted. Chulung Chen 陳祖龍 2008 學位論文 ; thesis 56 en_US |
