Several researches are conducted all over the world to design advanced, reliable tool and techniques to support sightless individuals. This paper describes designing of a handheld device to assist visually impaired people for color identification via generated speech. Vision is one of the five senses which is essential for a human being to survive independently. All individuals acquire the external information through the visual coding entering into the eye. The light rays penetrate and stimulate vision receptors to execute the processing of image formation. In response, the brain is able to identify the object. Unfortunately, any accidents or visual disorders with age can restrict the ability to sight the external environment. A visually impaired person can identify the texture, shape and size of an object by touching. But the sense of touch does not permit color identification. This proposed wearable tool, aid mainly focuses on individuals who are unable to observe colors due to visual disorder. A hardware device is presented which generates the speech for color detection. In this proposed work RGB sensor is used to capture the color information of the entity. An Arduino UNO card is programmed using Arduino software 1.6.3 to enhance the signal. It generates a clear audible speech for the specific color of the object. The benefit of this device is low power battery operated, portable, safe and easy to handle. 2017-01-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/13648 Title: Implementation of Fruit Grading & Sorting Station Using Digital Image Processing Techniques Authors: Mustafa Abro, Ghulam; Kumar, kundan Abstract: No doubt that today's technology has approximately solved many common as well as complex issues. Engineers and researchers are always in the quest for the best, brief and efficient methods to cope up the real world problems, hence fruit grading and sorting are one of the problems in export/import industry. In this regard industry requires a station that can check the skin of fruit, i.e. an apple whether it has rotten spots on it or not beside this whole procedure this specific station will also check the radius of an apple for sorting it further for packaging process. This whole procedure will be followed by a running conveyor belt, 2 AC plungers and a wooden box in between them, which will have 5 Mega pixel camera mounted on it. The camera will be triggered by a brief algorithm of digital image processing designed on the platform of MATLAB R2015a version and conclude whether the fruit, i.e. an apple is healthy or having some rotten spots on its skin. Once results are shown, then the algorithm will activate the respective plunger for grading and sorting of apples. 2017-01-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/13647 Title: 3D VIEW: Designing of a Deception from Distorted View-dependent Images and Explaining interaction with virtual World Authors: Muhammad Ali, Syed; Zeeshan, Mahmood; Qadri, Tahir Abstract: This paper presents an intuitive and interactive computer simulated augmented reality interface that gives the illusion of a 3D immersive environment. The projector displays a rendered virtual scene on a flat 2D surface (floor or table) based on the user’s viewpoint to create a head coupled perspective. The projected image is view-dependent which changes and deforms relative to user’s position in space. The nature of perspective projection is distorted and anamorphic such that the deformations in the image give an illusion of a virtual three dimensional holographic scene in which the objects are popping out or floating above the projection plane like real 3D objects. Also, the user can manipulate and interact with 3D objects in a virtual environment by controlling the position and orientation of 3D models, interacting with GUI incorporated in virtual scene and can view, move, manipulate and observe the details of objects from any angle naturally by using his hands. The head and hand tracking is achieved by a low cost 3D depth sensor ‘Kinect’. We describe the implementation of the system in OpenGL and Unity3D game engine. Stereoscopic 3D along with other enhancements are also introduced which further improves the 3D perception. The approach does not require head mounted displays or expensive 3D hologram projectors as it is based on perspective projection technique. Our experiments show the potential of the system providing users a powerful, realistic illusion of 3D. 2017-01-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/13646 Title: A Novel Minimization Method for Sensor Deployment Via Heuristic 2-Sat Solution Authors: Ahmed, Waleed; Ali, Muhammad; Rushdi, Ali Abstract: The tasks of guard placement or sensor deployment in an art gallery, a museum or in the corridors of public and security buildings pose the same problem, which requires placing the guards or sensors so as to cover a specified set of nodes with a minimum number of sensors or guards, thereby reducing the overall cost of the system as well assist power consumption. Generally, minimization can be done using optimization techniques such as linear programming, but in case of sensor deployment or guard placement there is a need either to place or not to place the sensor or guard, and hence only Boolean or binary values are used. Therefore, in order to optimize such a problem, we use the special case of linear integer programming known as Boolean integer linear programming (0-1 ILP). Other algorithms like Pseudo-Boolean SAT Solvers can also be used for the minimization purpose. In this paper, we introduce these minimization algorithms for the sensor deployment problem. We also contribute a greed-based heuristic, which utilizes the fact that the pertinent propositional formulas have variables of purely un-complemented literals. This heuristic has much less computational cost compared to those of 0-1 ILP and the Pseudo-Boolean SAT Solvers. 2017-01-20T00:00:00Z
