In the past few years the resolution of images increased and the requirement for large storage space and fast process, directly in the compressed domain, becomes essential. Fuzzy rule-based contrast enhancement, is a well-known rather simple approach with good visual results. As any fuzzy algorithm, it is by default nonlinear, thus not straightforward applicable on the JPEG bitstream data – zig...

An integrated system approach was developed to address the problem of distant speech acquisition in multi-party meetings, using multiple microphones and cameras. Microphone array processing techniques have presented a potential alternative to close-talking microphones by providing speech enhancement through spatial filtering and directional discrimination. These techniques relied on accurate sp...

Since the resolution of images increased in the past few years, the requirements for large storage space and fast process, directly in the compressed domain, becomes essential. Fuzzy rule-based contrast enhancement, is a well-known rather simple approach with good visual results, but as any fuzzy algorithm, it is by default nonlinear, thus not straightforward applicable on the JPEG bitstream (z...

Images with high resolution give better results for image processing applications. Image resolution enhancement is the process of manipulating an image so that resultant image is more suitable for specific application such as medical, agricultural, satellite image processing. This paper is based on image resolution enhancement by combination of SWT & DWT .In DWT main loss is on high frequency c...

We study the integration of multisensory and central input at the level of an identified fly motoneuron, the ventral cervical nerve motoneuron (VCNM) cell, which controls head movements of the animal. We show that this neuron receives input from a central neuron signaling flight activity, from two identified wide-field motion-sensitive neurons, from the wind-sensitive Johnston organ on the ante...

Two studies examined the interactive effects of different visual imagery perspectives and narcissism on motor performance. In both studies participants completed the Narcissistic Personality Inventory (NPI-40: Raskin & Hall, 1979) and were assigned to either an internal visual imagery or external visual imagery group. Participants then performed a motor task (dart throwing in Study 1 and golf p...

We have developed a technique for color image enhancement based on a model of the Human Visual System HVS A color image represented by RGB is rst transformed into a color space based on the HVS cone response characteristics Subsequently chromatic correlation reduction and energy compression is realized by using a multispectral Karhunen Lo eve transform KLT of the cone responses This yields a co...

introduction one of the most important pre-processing steps in optical coherence tomography (oct) is reducing speckle noise, resulting from multiple scattering of tissues, which degrades the quality of oct images. materials and methods the present study focused on speckle noise reduction and edge detection techniques. statistical filters with different masks and noise variances were applied on ...

Although a large number of methods have been proposed for low-light image enhancement, there still remain challenges these to simultaneously achieve excellent sharpness/resolution, high calculation efficiency as well visual pleasure requirements. In this communication, we propose new enhancement method based on the degradation model overcome dilemma. Specifically, regard special inverse problem...
