Vehicle logo recognition is an important part of vehicle identification in intelligent transportation systems. State-of-the-art vehicle logo recognition approaches typically consider training models on large datasets. However, there might only be a small training dataset to start with and more images can be obtained during the real-time applications. This paper proposes an online image recognition...
An efficient recognition framework requires both good feature representation and effective classification methods. This paper proposes such a framework based on a spatial Scale Invariant Feature Transform (SIFT) combined with a logistic regression classifier. The performance of the proposed framework is compared to that of state-of-the-art methods based on the Histogram of Orientation Gradients, SIFT...
This paper presents an analysis and design of a negative impedance converter (NIC) circuit for wideband matching of an electrically small antenna operating in the receive mode, and that stability work condition is also given. Experimental results presented demonstrate that the active receiving antenna exhibits good voltage gain and signal-to-noise ratio and that the active antenna is stable.
