A moving/parked car embeds mainly speed and momentum, and is surrounded by its environment. Both the cases are extremely unpredictable so, dynamically both the situations are handled. Any image captured is processed with edge detecting algorithm to recognize the number plate and simultaneously solve the problem of redundancy and speed issues in processing the image keeping visual quality. Keywo...

This paper concentrates on the optimisations and tradeoffs required to implement a colour segmentation based object tracking algorithm on a small Field Programmable Gate Array (FPGA). The algorithm consists of colour conversion, segmentation and labelling, morphological filtering, and bounding box based object recognition, and is able to track up to 4 independent coloured targets. By optimising...

Mathematical morphology is an implement for extracting image components that are helpful in the demonstration and explanation of region shape, boundaries, skeletons, and convex hull. Morphological operations are used in pre and post processing for thinning, filtering. Morphology is a development method used to extract image meaningful. In this paper, study the different morphology methods that ...

Abstract Aiming at the hopping time estimation problem of frequency (FH) signals under alpha stable distributed noise, a algorithm based on time-frequency pattern gradient sequence is proposed in this paper. Firstly, FH signal model and distribution noise are established according to received signals; Secondly fractional lower order SPWVD (FLOSPWVD) transform used suppress impulse pattern, clea...

background: butterworth, gaussian, hamming, hanning, and parzen are commonly used spect filters during filtered back-projection (fbp) reconstruction, which greatly affect the quality and size accuracy of image. materials and methods: this study involved a cardiac phantom in which 1.10 cm thick cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc conc...
