This paper studies an image descriptor that mimics the retina's photo receiving cell pattern. Various pattern differencing combinations and second order differencing techniques were explored. This new method shows higher precision and recall performance than the classical BRIEF and steered BRIEF descriptors.
Similarity measuring plays as an import role in stereo matching, whether for visual data from standard cameras or for those from novel sensors such as Dynamic Vision Sensors (DVS). Generally speaking, robust feature descriptors contribute to designing a powerful similarity measurement, as demonstrated by classic stereo matching methods. However, the kind and representative ability of feature descriptors...
In this paper, the problem of observer-based robust fault detection is studied for T-S fuzzy systems. A T-S model described fuzzy observer is considered as a fault detection filter to generate residual. The problem of fault detection is formulated into a model-matching problem so that the influence of uncertainty and disturbance is minimized to increase the robustness of residual to unknown inputs,...
Although the spatial SS (spread-spectrum) video watermarking algorithm had been proposed by many years, it is still a hot topic in watermarking community due to its good robustness. For watermarking algorithms based on SS, the embedding strength is always the key factor of robustness. Guided by the JND (Just Noticeable Distortion) model in DCT domain and the characteristics of DCT, a more reasonable...
This paper presents an accurate and flexible method for robust recognition and tracking of multiple objects in video sequence. We calculate color moments and wavelet moments for each detected object. Based on the extracted moment features, the SVM achieves optimal object recognition performance. The object recognition rate is above 98.53%. Since the tracking accuracy of feature matching method could...
We discuss the problem of soft errors in asynchronous burst-mode machines (ABMMs), and we propose two solutions. The first solution is an error tolerance approach, which leverages the inherent functionality of Muller C-elements, along with a variant of duplication, to suppress all transient errors. The proposed method is more robust and less expensive than the typical triple modular redundancy error...
