Image Point Motion When Zooming and Focusing
نویسنده
چکیده
A method for modeling the image point motion as function of the degree of zoom and focus is described and evaluated. The method requires that the camera can be translated towards a frontoparallel grid of calibration marks. The evaluation shows that, for a translation span of 2 meters, a zoom range from 10 to 96 millimeter, and for focus settings between 1 meter and innnity, the average prediction error for the zoom camera available is about 0.45 pixel.

Guiding robot motion using zooming and focusing
This work explores hand-eye coordination of robot by using a camera with functions of zooming and focusing. Under the guidance of the camera, a robot hand can arrive at an object to manipulate it in the 3D space. The hand movement is decomposed into the move parallel to the image plane and the move in depth, which are controlled from image position and focus value of the hand. The focal value i...
متن کاملImage Zooming using Non-linear Partial Differential Equation
The main issue in any image zooming techniques is to preserve the structure of the zoomed image. The zoomed image may suffer from the discontinuities in the soft regions and edges; it may contain artifacts, such as image blurring and blocky, and staircase effects. This paper presents a novel image zooming technique using Partial Differential Equations (PDEs). It combines a non-linear Fourth-ord...
متن کاملTuning Shape Parameter of Radial Basis Functions in Zooming Images using Genetic Algorithm
Image zooming is one of the current issues of image processing where maintaining the quality and structure of the zoomed image is important. To zoom an image, it is necessary that the extra pixels be placed in the data of the image. Adding the data to the image must be consistent with the texture in the image and not to create artificial blocks. In this study, the required pixels are estimated ...
متن کاملA New Technique for Image Zooming Based on the Moving Least Squares
In this paper, a new method for gray-scale image and color zooming algorithm based on their local information is offered. In the proposed method, the unknown values of the new pixels on the image are computed by Moving Least Square (MLS) approximation based on both the quadratic spline and Gaussian-type weight functions. The numerical results showed that this method is more preferable to biline...
متن کاملSuper-Resolution for Synthetic Zooming
Optical zooming is an important feature of imaging systems. In this paper, we investigate a low-cost signal processing alternative to optical zooming—synthetic zooming by super-resolution (SR) techniques. Synthetic zooming is achieved by registering a sequence of low-resolution (LR) images acquired at varying focal lengths and reconstructing the SR image at a larger focal length or increased sp...
