Respiratory motion is an important issue in radiotherapy as it can cause many problems such as damages to healthy tissues. Different methods have been introduced to estimate the respiratory motion but most of them need some electronic devices or ...

Traditional 3D graphics pipelines have been mostly implemented as fixed-function special-purpose hardware chips. Recently, introducing programmable graphics pipelines, there was dramatic changes in their implementations. Additionally, introducing ...

As the better high quality image is required for digital image scaling, longer processing time is required so the technology that can make the high quality image quickly is needed. We propose the double linear--cubic convolution interpolation creating ...

In this paper, we present a bio-health monitoring system prototype specialized in capturing the Premature Ventricular Contraction (PVC) event, one of the major cardiac disorder events. The proposed bio-health system comprises three parts: (1) the ...

In this paper, we propose a new image retrieval method based on Sectored Contour to Centroid Triangulation (SCTCT) using distinctive shape feature, named Arc Difference Rate (ADR). We utilized Support Vector Machine (SVM) method as an extraction tool to ...

This paper presents a high capacity reversible data embedding technique. It uses histogram modification in spatial and transform domains. It is a two level data embedding technique. In first level, embedding is done in spatial domain where a bit is ...

With the stereoscopic technology gradually maturing, realistic 3D devices are more and more popular. However, how to adapt current Web technologies to this booming trend still remains elusive. In this paper, a novel approach to support stereoscopic 3D ...

This paper presents an evaluation of different methods considering the usually problems in face recognition. We consider variations in illumination, facial expression and facial details to propose a new method combining global and local face image ...

Binary descriptors have recently become very popular in visual recognition tasks. This popularity is largely due to their low complexity and for presenting similar performances when compared to non binary descriptors, like SIFT. In literature, many ...

Smart phones with optical sensors have created new opportunities for low cost and remote monitoring of vital signs. In this paper, we present a novel approach to find heart rate, perfusion index and oxygen saturation using the video images captured by ...

One of the main issues related to the treatment of soybean seeds concerns its vigor definition. The great majority of vigor analysis is performed by a human specialist leading to an extremely tiresome and subjective approach, highly susceptible to ...

Content-aware image retargeting is the problem of adapting images to different display sizes and aspect ratios while minimizing distortions to the most important regions of those images. Seam carving is an operator for content-aware image retargeting ...

Coherent X-ray scattering is an emerging technique for measuring structure at the nanoscale. Data management and analysis is becoming a bottleneck in this technique. We present an unsupervised method which can sort and cluster the scattering snapshots, ...
