In this paper, we propose a new strategy for near-duplicate video retrieval that is based on shot aggregation. We investigate different methods for shot aggregation with the main objective to solve the difficult trade-off between performance, scalability and speed. The proposed short aggregation is based on two steps. The first step consists of keyframes selection. And the second one is the aggregation...
The accuracy of the Three-Cornered Hat method is discussed when not simultaneously applied to the determination of the contribution on short term frequency stability performed on ultra-stable quartz oscillators.
In this paper we propose a framework for automatically chaptering VoD content based on its DVD version. The idea is to benefit from artistic work performed for DVD chapter creation even if DVD and VoD video content are not exactly the same. The framework is based on a sparse to dense frame synchronization, combining both global and local image descriptions, together with adaptive video sequence splitting...
The aim of this article is to present the performances of the instruments developed for the measurement of 5 MHz ultra-stable resonators, before and after being integrated in an oscillator. The chosen resonator has an estimated stability of several 10−14. Intrinsic noise floor of these benches are about 7 to 9.5×l0−15.
