The aim of this work is to overcome the narrow surgical field of view problem in minimally invasive surgery. We achieve this by combining multiple views of the camera-retractable trocar which can obtain surgical viewpoints different from laparoscopic view. However, the accuracy and time are essential factors in this process. Therefore, we tend to improve the accuracy of a hybrid tracking-mosaicking...
In this work, an approach for Arabic handwriting word segmentation is proposed. In this approach words are over-segmented and the segmentation points (SPs) are then validated. As the validation stage accuracy controls the whole system accuracy, an improved validation approach is proposed to alleviate other approaches' limitations and enhances the accuracy. In this validation approach, a set of zoning...
This work presents an automatic approach for liver lesions detection in CT images. In this approach, liver is first segmented using fast and reliable semi-automatic technique. After liver segmentation, lesion detection is formulated as an unsupervised segmentation approach to alleviate tedious user interaction or prior learning requirements. The Meanshift clustering technique is utilized to separate...
In this paper, we study two-hop communication protocol in presence of Additive Class-A impulsive noise, where relay nodes assist in the communication between two terminals. The terminals operate in half-duplex mode; hence the transmission of one information symbol from the source terminal to the destination terminal occupies two time slots. This leads to a loss in spectral efficiency due to the per-log...
