The normalized state |ψ(t)〉 = c1(t)|1〉 + c2(t)|2〉 of a single two-level system performs oscillations under the influence of a resonant driving field. It is assumed that only one realization of this process is available. We show that it is possible to approximately visualize in real time the evolution of the system as far as it is given by |c2(t)| 2. For this purpose we use a sequence of particu...

The main aim of this paper is to show the utility of cokriging for image fusion (i.e. increasing the spatial resolution of satellite sensor images). It is assumed that co-registered images with different spatial and spectral resolutions of the same scene are available and the task is to generate new remote sensing images at the finer spatial resolution for the spectral bands available only at t...

with the development in the digital imaging techniques, an image enhancement is one of the characteristic of image. The medical image enhancement is one of the application, these data can be suffer from some of the unnecessary noise, lack of contrast, sharpening and distort images due to these flaws we obtain false report for diagnosis of diseases. So for improving the quality of the medical im...

There are many systemic diseases that affect the functioning and working of the eye. Some of the major parts of the eye like iris, retina, and optic nerve are affected due to systemic diseases like diabetes, AIDS, glaucoma, hypertension, macular degeneration, swelling in the brain and many more. Glaucoma is the condition of eye caused by increase in intraocular pressure. Early detection of this...

The novel approach to the image sharpening problem is proposed in this paper. It is based on the application of the independent component analysis (ICA) algorithm on the image sequence with the appropriate time displacement between the image frames. The novelty is in the data representation required by the ICA algorithms where each selected image frame has been used as a sensor implying that un...

The assessment of the performance of multi-resolution image fusion, or image sharpening methods, is difficult. In the context of binary classification of snow targets in mountainous terrain, fusion methods were applied to help achieve more accurate mapping. To quantify objectively the gain of information that can be attributed to an increase in spatial resolution, we investigate the Mean Euclid...

Hung-Shing Chen Shih-Han Chen Abstract — Owing to the fast developments of computer networks and color imaging technologies, there is a tendency towards remote proofing in the printing or textile industries. More cases such as cross-display color matching will occur in the future information society. The problems of color mismatching we usually find in cross-display devices have been widely dis...

 Fast Single Image Super-resolution by Self-trained Filtering Dalong Li, Steven Simske HP Laboratories HPL-2011-94 Super-resolution; PSNR; filter; image restoration; image enhancement This paper introduces an algorithm to super-resolve an image based on a self-training filter (STF). As in other methods, we first increase the resolution by interpolation. The interpolated image has higher resolu...

Traditional error di usion halftoning is a high quality method for producing binary images from digital grayscale images. Error di usion shapes the quantization noise power into the high frequency regions where the human eye is the least sensitive. Error di usion may be extended to color images by using error lters with matrix-valued coe cients to take into account the correlation among color p...
