In this paper, a novel image enhancement system for a wide-angle lens camera is presented. The proposed system consists of; i) lens distortion correction using space-varying interpolation kernels and ii) image restoration based on the local self-simi

A modified regularization algorithm is proposed to enhance compressed video by restoring predictive-coded pictures. Since most video coding standards adopt a hybrid structure of macroblock-based motion compensation and block discrete cosine transform

A novel white point estimation method is presented for automatic white balance (AWB). The proposed method first detects white points by estimating dark channel prior information in the input image, and then adjusts the white balance on the detected w

This paper presents a regularized iterative image interpolation algorithm, which can restore high frequency details in the original high resolution image. In order to apply the regularization approach to the interpolation procedure, we first present

This paper presents a novel real-time super-resolution (SR) method using directionally adaptive image interpolation and image restoration. The proposed interpolation method estimates the edge orientation using steerable filters and performs edge refi

We present an antialiasing method using combined wavelet-Fourier transform and spatially adaptive shrinkage of the transform coefficients. Traditional antialiasing methods employ a simple low-pass filter onto the entire image, so the resulting image

Light field camera is gaining its popularity since it allows users to refocus a captured image. But it is not easy to obtain a high quality all-in-focus image even though each sub-image has wide depth-of-field. Existing methods generate refocused ima

As pixel size of image sensors shrinks down rapidly, we are reaching technical barrier to get the required low light performance. In this paper, recent advanced technologies such as backside illumination, new color filter array, low F-number with ext

Video tracking systems are inherently provided with non-rigid objects with various shapes and sizes, which often result in poor match of an initial model with the actual input shape. The hierarchical approach to the active shape model(ASM) is essenti
