Abstract In microwave or synthetic aperture radar or radar image formation, a speckle noise is generally added. This noise is available in coherent imaging systems like radar image capturing, medical image capturing, etc. De-speckling methods are used to de-speckle the available speckle noise from these speckled systems. In optical image formation, other noises are added.An […]
Abstract In this paper, the performance of the signal and denoising techniques using different types of Wavelet Transform techniques is evaluated based on the different performance metrics such as Signal to Noise Ratio(SNR). A new Complex Wavelet Transform technique called Hybrid Dual Tree Complex Wavelet Transform, has been proposed in this work, so as to […]
Abstract In Present days we are going with paperless environment for the documentation purpose in order to save the lives of trees. The documents may consists of text, symbols, tables, graphs, logos and signatures and other features also. Out of all these features the signature and logos are having their own unique properties in the […]
Abstract Change detection techniques are playing major role in order to know the changes in different situations. Using these methods, we can know the changes that are occurred or occurring on earth due to climatically changes or degradation of certain areas. Change detection will help us to observe the different areas on earth remotely. The […]
Abstract Classification of images obtained from satellites is a challenge now-a-days in order to know the information contained by them. This requires the adaption of the present state-of-art classifiers. Correct information can be retrieved only with good classification method. But single classifier may not meet the requirement, so that ensemble techniques are preferable. For classification […]
Abstract This paper reflects the design and comparison of different Phase Frequency Detectors (PFD) used in Phase Locked Loop (PLL) using different logic gates. A PFD plays a major role in PLL, it detects both phase and frequency of a signal. In this paper a PFD is implemented using three different gates like AND, NOR […]
Abstract Traffic light controlling becomes major issue with increase in automobiles and it also must to reduce time delays while going in traffic from long time delays at traffic signals. So, on considering this problem, we will go with Smart Traffic light signalling system using IR Sensors. This article explains how to reduce time delays […]
Abstract These days, as the rate of heart ailments expanding progressively, electrocardiogram [ECG] an essential apparatus to analyze the different issues relating to heart. Yet, the recorded ECG frequently contains ancient rarities like electrical cable commotion, gauge clamor, and muscle antiquities. Subsequently denoising of ECG signals is vital for exact analysis of heart ailments. To […]
Abstract The target of image compression is to diminish insignificance and repetition of the picture information keeping in mind the end goal to have the capacity to store or transmit information in a proficient manner. The change from the cine film to advanced strategies for picture trade and authentic is basically persuaded by the simplicity […]
Abstract In correct registering is a growing world outlook for computation at nanoscale for error tolerant applications like in multimedia and image processing. PC number juggling offers critical operational focal points for estimated figuring, a broad writing exists on rough adders. However, this paper has concentrates on compression based multiplier design, which offer major advantages […]
