When the size of an image such LIS Q picture OT a painting is beyond the scope of Q camera, it is dificult t o take the whole picture which is high resolution image all a t once. In this case, each part of the image is taken b y camera one by one. The par t of the image is an image patch. Using the image patches, the whole picture is reproduced. This method is called the image mosaicing method....

In this technical report, we address the problem of recovering the camera radial distortion coefficients from one image. In particular, we present three interactive methods where the user indicate lines in the single image. The first method is the most direct: the manually chosen points are used to compute the radial distortion parameters. The second and third methods allow the user to draw sna...

High speed imaging by atomic force microscopy (AFM) allows one to directly observe the dynamic behavior of a sample surface immersed in liquid media; thus, it has been considered to be an indispensable tool for nanobiotechnology and is used in many research fields, including molecular biology and surface science. For real-time observation of a certain behavior, the high speed imaging technique ...

Modern video-based endoscopes offer physicians a wide-angle field of view for minimally-invasive procedures. Unfortunately, inherent barrel distortion prevents accurate perception of range. This makes measurement and distance judgment difficult and causes difficulties in emerging applications, such as 3D medical-image registration. Such distortion also arises in other wide field-of-view camera ...

Distortion in the ISAR image of a target is a result of nonuniform rotational motion of the target during the imaging period. In many of the measured ISAR images from moving targets, such as those from in-flight aircraft, the distortion can be quite severe. Often, the image integration time is only a few seconds in duration and the target’s rotational displacement is only a few degrees. The con...

Several color image delity metrics are evaluated by comparing the metric predictions to empirical measurements. Subjects examined image pairs consisting of an original and a reproduction. They marked locations on the reproduction that differed detectably from the original. We refer to the distribution of error marks by the subjects as image distortion maps. The empirically obtained image distor...

In this paper, an optimized quantization of wavelet transform coefficients and low complex distortion control system for image compression is proposed. Distortion control is an important issue in maintaining the desired quality in the retrieved signal of compressed data. We construct a linear relationship between the distortion and quantization scale, which is crucial for efficient quality main...

A very important property of the usual pinhole model for camera projection is that 3D lines in the scene are projected to 2D lines. Unfortunately, wide-angle lenses (specially low-cost lenses) may introduce a strong barrel distortion, which makes the usual pinhole model fail. Lens distortion models try to correct such distortion. In reference 1., we propose an algebraic approach to the estimati...
