In this paper we present a signal-theoretical model of the aliasing in the triplet stripe filter CCD image selisor. In this sensor, the colour filters are placed in a repetitive pattern of three columns on the monochrome sensor. Therefore the projected scene is sampled at every three columns and aliasing can result. We use the signal-theoretical model to predict the visibility of the aliasing.

This paper discusses the effects of frequency selection on source localization and geoacoustic inversion methods that use frequency coherent objective functions. Matched-field processors based on frequency-coherent objective functions often have rapidly fluctuating range ambiguity surfaces. Insufficient sampling in frequency domain results in range aliasing terms that affect geoacoustic inversi...

Pixel art is a unique style with the appearance of low resolution images. In this paper, we propose data-driven pixelization method that can produce sharp and crisp cell effects controllable sizes. Our approach overcomes limitation existing learning-based methods in size control by introducing reference pixel to explicitly regularize structure. particular, structure features are used as an auxi...
