A documenZ can be divided inio zones on the basia of ils content. For ezample, a zone can be either tezt or non-tezt. This paper describes an algorithm to classify each given document zone into one of nine diflerent classes. Features for each zone such as run length mean and variance, spatial mean and variance, fraction of the total number of black pizels(More)
This work focuses on the modelling and simulation of 3-PRS (Prismatic - Revolute - Spherical) Tripod Parallel Manipulator. This tripod mechanism consists of base platform and movable platform, which are connected by means of three links or limbs. Spherical joints are used to connect one end of the link and the moving platform and the other end of the link(More)
Now-a-days robots have occupied a space for themselves in our daily routine life. Modern robots are proficient to execute the complex tasks from like Space Exploration, Nuclear Inspection, Manufacturing, etc to the simple tasks like pick and place. The robots are developed to execute their specified task in the 3-D space. The end-effector of the robot is(More)
Robots have occupied an important role for themselves in our everyday life. Recent advanced robots are capable to do the various complex responsibilities as manufacturing of precise components, Space exploration, nuclear equipment installations and inspection etc to the regular responsibilities as palletizing, pick and place operations. The robots are(More)
Three dimensional (3-D) vision techniques in the field of Computer Vision aims mainly at reconstructing a scene (surface) to find its three dimensional geometrical information from 2D image(s) and sometimes with the aid of some special devices. Passive 3-D vision techniques such as computational stereo vision method do surface reconstruction from(More)
Shape From Focus (SFF) is a widely researched technique in the field of computer vision for scene reconstruction. The SFF technique exploits the fact that the pixel focus preserves depth information. The SFF technique is based on estimation of focus levels of pixels in a stack of images acquire from different focal distances. SFF requires telecentric lenses(More)
Three dimensional (3-D) vision techniques in the field of Computer Vision aims mainly at reconstructing a scene to find its three dimensional geometrical information. Passive 3-D vision techniques such as computational stereo vision method do surface reconstruction from disparities arising in images of the same scene taken from multiple views. For(More)
Shape from Focus (SFF) is a method which recovers the 3D geometry of the scene based on a sequence of images taken from different focus distances between the camera and the object. Generally SFF techniques require parallel projection of the scene on to the image plane so that the corresponding pixels in the set of images taken are easily identified. This(More)
