This paper proposes a new algorithm using global and local features for content-based image retrieval. Global features are extracted using the magnitude of Zernike moments (ZMs). Local features are obtained through local directional pattern (LDP). Generally, LDP is used to extract texture-based features from an image. In this paper, LDP is used to encode both texture and shape information of an image...
Digital watermarking has developed immensely for multimedia uses in the current decade. The requirement for protected digital content grows vital with the enhancement in exchange of digital images on internet. Watermarking is a technique to safeguard digital media by retaining the owner's possession. Fingerprinting extends the watermarking concept by embedding unique purchaser's information. This...
This paper presents an efficient approach to find optimal power flow (OPF) determining the dispatch schedule of power generators with minimum cost while satisfying the system constraints like the upper and lower power and reactive power generation limit, upper and lower voltage level limit, and line flow limit using power world simulator. The minimization of the generation cost will result to a lower...
