We consider the problem of finding the localization of radioactive source by using data from a digital camera. In other words, the camera could help us to detect the direction of radioactive rays radiation. Therefore, the outcome could be used to command a robot to move toward the true direction to achieve the source. The process of camera data is performed by using image processing and computa...

in this paper, a new method for determining position and orientation of a coordinate system using its image is presented. this coordinate system is a three dimensional non-orthogonal system in respect to the two dimensional and orthogonal camera coordinate system.  in real world, it’s exactly easy to select three directions on an object so that they don’t be orthogonal and on a plane. the image...

potato image segmentation is an important part of image-based potato defect detection. this paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on genetic algorithm (ga) optimization and morphological operators. the proposed potato color image segmentation is robust against variation of background, distance and ...

volume estimation of most agricultural products using mathematical methods is not accurate because of their irregular shape. an alternative method is image processing, which can be used in continuous sorting machines. the objective of this study is to find a practical method for volume estimation of potatoes using image processing. fifty potatoes (marfona variety) were selected as experimental ...

Digital cameras are becoming more powerful and affordable with each product generation. This paper describes a new generation digital camera that optimizes image quality and ease of use. Excellent image quality is obtained by employing a megapixel CCD sensor and advanced image processing algorithms. A 1.8” color LCD and a new graphical user interface (GUI) guide the user through the operation o...

Security monitoring, event detection and tracking of people are a few of the well-known applications for indoor video surveillance systems, but mainly they are accomplished by visual inspection of the images. There is need to integrate visual surveillance systems with 3D geospatial data to semantically improve interpretation of scene dynamics which is challenge in 2D image analysis. In this stu...
