Abstract

This paper proposes an interpolation algorithm for conversion from the interlaced to the progressive scanning format. The proposed algorithm consists of two parts: an edge direction detection part and a fuzzy rule-based edge-restoration interpolation part. The different types of edge, peak, and monotonic slope patterns are considered in a spatial domain interpolation strategy. Edges with a certain vertical component look preserved in the interpolation using a fuzzy rule-based algorithm. The vertical resolution in the interpolated image is subjectively concealed by introducing vertical gradients in the interpolation. Computer simulations verify the effective performance of this image processing technology.
