Compression of hyperspectral images based on Tucker decomposition and CP decomposition
Journal of the Optical Society of America A, 2022Hyperspectral imagers are developing towards high resolution, high detection sensitivity, broad spectra, and wide coverage, which means that hyperspectral data are getting more and more substantial. This brings a great challenge to data storage and real-time transmission of hyperspectral data.

CP tensor-based compression of hyperspectral images
Journal of the Optical Society of America A, 2017In this paper, an effective CANDECOMP/PARAFAC tensor-based compression (CPTBC) approach is proposed for on-ground hyperspectral images (HSIs). By considering the observed HSI cube as a whole three-order tensor, the proposed CPTBC method utilizes the CANDECOMP/PARAFAC tensor decomposition to decompose the original HSI data into the sum of R rank-1 ...

A Fast Image Denoising Method Based on CP Tensor Analysis
2021 IEEE 6th International Conference on Computer and Communication Systems (ICCCS), 2021The data represented by tensor can maintain its original form, which is conductive to preserving high dimensional structure and adjacent relation information of data. Tensor factorization plays an instrumental role in signal processing, especially image processing.

Image restoration in chirp-pulse microwave CT (CP-MCT)
IEEE Transactions on Biomedical Engineering, 2000Chirp-pulse microwave computed tomography (CP-MCT) is a technique for imaging the distribution of temperature variations inside biological tissues. Even if resolution and contrast are adequate to this purpose, a further improvement of image quality is desirable.

Image Restoration of CP-MCT for Sugar Distribution Imaging inside a Fruit
2006 European Microwave Conference, 2006But for water, the main component of a fruit is sugar. Most of the fruits contain sugar from 8 % to 22 % by weight at the harvest time. According to our preliminary study, chirp pulse microwave computed tomography (CP-MCT) has a possibility of measuring sugar content distribution nondestructively.

Imaging capability of an early stage breast tumor by CP-MCT
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Capability of diagnostic imaging of an early stage breast tumor using microwaves has been investigated by means of FDTD-based numerical simulations. More than ten years ago, we developed chirp pulse microwave computed tomography (CP-MCT) for microwave imaging of a human body.

CP-PSIS: CRT and polynomial-based progressive secret image sharing
Signal Processing, 2021Abstract In (k, n) Progressive Secret Image Sharing (PSIS) schemes, n shares are obtained by sharing a secret image. With k to n shares, the secret image can be recovered progressively. No information of the secret image can be constructed by k-1 or fewer shares.

Imaging of forearm-muscle activities by CP-MCT and TR-DOT
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009Chirp Pulse Microwave Computed Tomography (CP-MCT) has been developed to visualize activities of forearm muscles during exercise. The change in the gray levels between two images obtained before and after loading exercises showed position dependence.

Improved HOG Descriptors in Image Classification with CP Decomposition
2013Histogram of Oriented Gradients (HOG) has been widely used in computer vision as feature descriptors for detecting objects in scenes. We present in this paper a new approach to HOG in image classification that will provide an opportunity to explore new ways to improve the effectiveness of HOG image descriptors.

A high-resolution photoelectron imaging and theoretical study of CP− and C2P−
The Journal of Chemical Physics, 2018The discovery of interstellar anions has been a milestone in astrochemistry. In the search for new interstellar anions, CP− and C2P− are viable candidates since their corresponding neutrals have already been detected astronomically. However, scarce data exist for these negatively charged species.
