Currently, the price of digital camera is decreasing and many users afford to purchase it. The digital camera can be used for many applications. The digital camera can also be used for accurate measurement such as determination of three dimensional (3D) coordinates, production of accurate measurement and generation of 3D model of objects. However, the digital camera need to be calibrated to obtain...
In the field of geoinformation, geographic information can be converted into plan in the form of two dimensional (2D) using geomatic method that is using tacheometric technique and total station instrumentation. Topographic and thematic maps in 2D can be produced using photogrammetric technique. In photogrammetry, the three dimensional (3D) stereomodel can be used to generate 3D model. Today, 3D model...
Three-dimensional (3D) colour-coded mapping of dominant frequency (DF) from noncontact unipolar electrograms in real-time can serve as a powerful tool for identifying potential atrial fibrillation (AF) drivers allowing the analysis and identification of re-entrant circuits sustaining AF. The main problems with the current technology of 3D DF mappings are the lack of spatial resolution and the long...
In this research, novel architectures based on different design approaches and arithmetic techniques such as direct mapping implementation, dynamic partial reconfiguration (DPR) mechanism, distributed arithmetic (DA) and systolic array (SA) will be developed for three dimensional (3D) medical image compression system. Moreover, solutions for processing large medical volumes will be investigated and...
This paper describes the design and implementation of 3D Haar wavelet transform (HWT) with transpose based computation and dynamic partial reconfiguration (DPR). As a result of the separability property of the multi-dimensional HWT, the proposed architecture has been implemented using a cascade of three N-point 1D HWT and two transpose memory for a 3D volume of N ?? N ?? N, suitable for 3D medical...
