A New Method to Optimize Initial Cluster Number and Then Apply K-Means Algorithm to Perform Image Segmentation
Abstract: Clustering is described as the task of merely grouping a set of data points, which in our case are represented by image pixels, with the application of one or more algorithms, into super-pixels. The k-means clustering algorithm is used for many day-to-day practical applications where the quality of the obtained clusters depends heavily on the initial selection of centroids. In literature, several methods have already been proposed for the improvement …

Note Repositioning Algorithm for Musical Instruments in Indian Classical Music
Abstract: Abstract: Indian classical music has two broad aspects; the vocalists and the instrumentalists. The vocalists are often accompanied by the instrumentalists who follow the singing of the vocalists. To produce enriching and pleasant music, the instrumentalist has to match the tonal quality of vocalist. This can be achieved by the instrumentalist repositioning the notes played on his instrument. The instrumentalist has to play the same music on different notes, which …

Greedy Algorithm
Abstract: In mathematics and computer science, an algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal choice at each stage[1] with the hope of finding a global optimum. In many problems, a greedy strategy does not in general produce an optimal solution, …
