Parallel Beamformation Method to Enhance Ultrasound Images
Contrast resolution and detail resolution are two important parameters in ultrasound imaging. This paper presents a new method to enhance these parameters, simultaneously. A parallel auxiliary beamformer has been employed whose weightings are such that an estimation of the leaked signal through the main beamformer is obtained. Then the output of main beamformer is modified according to the ...
متن کاملTowards a Hybrid Approach to Context Reasoning for Underwater Robots
Ontologies have been widely used to facilitate semantic interoperability and serve as a common information model in many applications or domains. The Smart and Networking Underwater Robots in Cooperation Meshes (SWARMs) project, aiming to facilitate coordination and cooperation between heterogeneous underwater vehicles, also adopts ontologies to formalize information that is necessarily exchang...
متن کاملA Robust Quasi-dense Matching Approach for Underwater Images
While different techniques for finding dense correspondences in images taken in air have achieved significant success, application of these techniques to underwater imagery still presents a serious challenge, especially in the case of “monocular stereo” when images constituting a stereo pair are acquired asynchronously. This is generally because of the poor image quality which is inherent to im...
متن کاملA Hybrid Approach for Denoising Dicom Images
This paper provides a new model based on the hybridization of wavelet and relaxed median filter for denoising of noisy medical images. The present study focuses on proposing a technique to reduce speckle and salt & pepper noise from CT (Computed Tomography) scan devices. In diagnosis of diseases, devices are frequently used by healthcare professionals. The main problem during diagnosis is the d...
متن کاملA Signal Processing Approach to Estimate Underwater Network Cardinalities with Lower Complexity
An inspection of signal processing approach in order to estimate underwater network cardinalities is conducted in this research. A matter of key prominence for underwater network is its cardinality estimation as the number of active cardinalities varies several times due to numerous natural and artificial reasons due to harsh underwater circumstances. So, a proper estimation technique is mandat...
