Despite the advances in machine learning techniques, similarity assessment among
multimedia data remains a challenging task of broad interest in computer science …

In this paper, we propose an extremely efficient algorithm for visual re-ranking. By
considering the original pairwise distance in the contextual space, we develop a feature …

Generally, discrete orthogonal moments are difficult to induce rotation invariants. Based on
relationship between Tchebichef polynomials and power series, we propose a new …

In its most widespread imaging and vision applications, Ambrosio and Tortorelli (AT) phase
field is a technical device for applying gradient descent to Mumford and Shah simultaneous …

Nowadays there are many efforts to develop image matching applications exploiting a large
number of images stored in smart devices such as smartphones, smart pads, and smart …

Recently, a variety of smart devices have been introduced for entertainment or industrial
purposes, and there have been a lot of needs for image matching applications exploiting a …
