Introduction: Cone beam computed tomography (CBCT) was introduced and became more common based on its low cost, fast image procedure rate and low radiation dose compared to CT. This imaging modality improved diagnostic and treatment-planning procedures by providing three-dimensional information with greatly reduced level of radiation dose compared to 2D dental imaging modalitie...

the alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. the p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. the skeleton be considered as a r...

-A reliable method for extracting structural features from fingerprint images is presented. Viewing fingerprint images as a textured image, an orientation flow field is computed. The rest of the stages in the algorithm use the flow field to design adaptive filters for the input image. To accurately locate ridges, a waveform projection-based ridge segmentation algorithm is used. The ridge skelet...

Image Skeletonization promises to be a powerful complexity-cutting tool for compact shape description, pattern recognition, robot vision, animation, petrography pore space fluid flow analysis, model/analysis of bone/lung/circulation, and image compression for telemedicine. The existing image thinning/skeletonization techniques using boundary erosion, distance coding, and Voronoi diagram are fir...

Brain tumor detection is still a challenge in the field of brain compute-aided diagnosis. In the brain Magnetic Resonance Images (MRI), the correlation between lateral ventricles deformations and tumor existence has been found useful in brain tumor detection and prediction. To retrieve the lateral ventricles deformation data for further statistical analysis and processing, a new method has been...

Reactive navigation is the most researched technique for underground vehicles. Local path planning one of main research difficulties in reactive navigation. At present, no can perfectly solve problem local Aiming to address this problem, paper proposes a new method based on 2D LiDAR. First, we convert LiDAR data into binary image, and then extract skeleton image through thinning algorithm. Fina...

In this paper, we present our approach to developing a general framework for FPGA based Image Processing. This framework is based on a library of Hardware Skeletons. A hardware skeleton is a parameterised description of a task-specific architecture. A skeleton’s implementation will apply optimisations specific to the target hardware. The library normally contains a range of alternative skeleton...

Root system architecture (RSA) plays an important role in plant development and survival. The ability to accurately model and quantify properties of root architecture is fundamental for sustainability studies, crop improvement, and studies of plant-microbal interactions. Existing methods to model RSA either require a dense set of images or rely on 3D scanning methods for dense reconstruction. I...

An important step in studying the statistics of fingerprint minutia features is to reliably extract minutia features from the fingerprint images. A new reliable method of computation for minutiae feature extraction from fingerprint images is presented. A fingerprint image is treated as a textured image. An orientation flow field of the ridges is computed for the fingerprint image. To accurately...

Image processing is widely used in many applications, including medical imaging, industrial manufacturing, and security systems. Often the size of the image is very large, the processing time has to be very small and usually real-time constraints have to be met. Therefore, during the last decades there has been an increasing interest in the development and the use of parallel algorithms in imag...
