概要

• 論文の詳細を見る

• This paper presents non-parametric sharpness-enhancing enlargement technique for Terahertz images that combines spatial interpolation and discrete wavelet transform (DWT) reconstruction. The proposed algorithm finds the details from a DWT analysis of an interpolated version, then an inverse DWT of the details and the approximation rescaled from the input image produces an enlarged image. The computer simulation shows the proposed method shows higher peak signal-to-noise ratio and the sharpness measured by Tenengrade and sum-modulus-difference (SMD) than popular image enlargement algorithms.
