This paper investigates the detection of object using depth information that obtained from Kinect sensor. Type and distance of object have been investigated in order to find the best parameter in detecting objects. Two types of object are experimented; shiny and curved shape of object and dull and flat shape of object. Various distances of objects from the Kinect have been tested. From the results...
Fundus images provide an opportunity for early detection of diabetes. Generally, retina fundus images of diabetic patients exhibit exudates, which are lesions indicative of Diabetic Retinopathy (DR). Therefore, computational tools can be considered to be used in assisting ophthalmologists and medical doctor for the early screening of the disease. Hence in this paper, we proposed visualisation of exudates...
Automatic Optic Disc (OD) removal is vital step prior to screening Diabetic Retinopathy (DR) cases. Hence in this paper, we proposed an automated technique for removal of OD position in digital retina fundus images based on mathematical morphological operations. Here, dilation and erosion to remove OD and enhance the appearance of binary images. The proposed technique was tested on 400 images of the...
This paper presents a blind watermarking algorithm for medical images and medical video frames based on Principle Component Analysis (PCA) and Digital Wavelet Transform (DWT). Quantization Index Modulation (QIM) is used as a method for blindness of our scheme. Different types of medical video frames are used in the evaluation process such as MRI, CT, Ultrasound and X-Rays. Experimental results show...
In this paper, a comprehensive approach for digital video watermarking is introduced, where a binary watermark image is embedded into the video frames. Each video frame is decomposed into sub-images using 3 level discrete wavelet transform then the Principle Component Analysis (PCA) transformation is applied for some selected blocks. The selection of the blocks depends on calculating the entropy of...
The delay reduction of logic architecture leads to the reduction in costs associated with the development time, fabrication (chip area), and power requirements, as well as increased performance. The logical effort technique provides an easy way to compare and select circuit topologies, choose the best number of stages for path and estimate path delay. The Particle Swarm Optimization method is proposed...
The demand on electricity consumption in Egypt has rapidly increased during the last two decades. The installed capacity increased from 2240 MW in year 1981 to 14600 MW in year 2003, whereas the electricity consumption increased from18 TWh to 79.8 TWh during the same period. The annual increase in electricity consumption within the last five-year plan 1997–2002 reached 7.6%. The Ministry of Electricity...
