Web12 dec. 2024 · In contrast, one-shot imaging is conducted using one electron pulse for acquisition of a TEM image or an electron energy-loss (EEL) spectrum within a certain detection time period. When the frame rate of the imaging sensor is exceeded, a time series of one-shot TEM images are arranged on the sensor using a fast electric deflector [ 27 ]. Web13 jan. 2024 · This article proposes a denoising method based on sparse spectral–spatial and low-rank representations (SSSLRR) using the 3-D orthogonal transform (3-DOT). SSSLRR can be effectively used to remove the Gaussian and mixed noise. SSSLRR uses 3-DOT to decompose noisy HSI to sparse transform coefficients. The 3-D discrete … people\\u0027s backgrounds

A noise level … WebPansharpening refers to the super resolution of a low-resolution multispectral (LR-MS) image in virtue of an aligned panchromatic (PAN) image. Such an inverse problem mainly requires a proper use of the spatial information from the auxiliary PAN image. In this paper, we suggest a nonconvex regularization model for pansharpening via framelet sparse … people\\u0027s background examples
