Looking for a bird's-eye view of human impacts? A new study, published in the journal Nature, provides the most comprehensive picture yet of how human noise and light pollution affect birds throu...
西安电子科技大学高频电子线路课件chapter5 Low Noise Amplifiers。
The definition, renewal and maintenance of geodetic datum has been international hot issue. In recent years, many countries have been studying and implementing modernization and renewal of local geode...
The SAE 2017 Noise and Vibration Conference and Exhibition is the premier technical event dedicated to mobility noise, vibration and harshness. Held biennially, this conference serves as a forum for l...
In the environment of farms and farm buildings, cattle are exposed to various unnatural influences. Such an impact is also noise always arising with a certain energy conversion. In cattle farms, the s...
The SAE 2017 Noise and Vibration Conference and Exhibition is the premier technical event dedicated to mobility noise, vibration and harshness. Held biennially, this conference serves as a forum for l...
To serve seamless mapping, airborne LiDAR data are usually collected with multiple parallel strips with one or two cross strip(s). Nevertheless, the overlapping regions of LiDAR data strips are usuall...
Noise is an important factor that influences image quality, which is mainly produced in the processes of image acquirement and transmission. Noise reduction is necessary for us to do image processing ...
Since the European Space Agency Mars Express spacecraft entered an orbit around Mars, the High Resolution Stereo Camera (HRSC) placed onboard has been imaging the Martian surface. Due to the character...
Speckle noise caused by interference of electromagnetic waves complicates Synthetic aperture radar (SAR) images to be interpreted and further practical application, therefore reducing speckle noise an...
In the paper the use of wavelet transformation for valorization of random noise content in photogrammetric images is proposed. There were two wavelets indicators studied. The first indicators based on...
The AHS is an 80-bands airborne imaging radiometer, operated by INTA in different remote sensing projects. It has 63 bands in the reflective part of the electromagnetic spectrum, 7 bands in the 3 to ...
Overcomplete representations are attracting interest in signal processing theory, particularly due to their potential to generate sparse representations of signals. However, in general, the problem o...
Consider the noisy underdetermined system of linear equations: y = Ax0 + z0, with n  N measurement matrix A, n < N, and Gaussian white noise z0  N(0; 2I). Both y and A are known, both x0 and z0 are...
Reduction of speckle noise is one of the most important processes to increase the quality of radar coherent images. Image variances or speckle is a granular noise that inherently exists in and degra...
