Size Distribution Estimation Method using Reflected Laser Light Angle Dependency by Rain Droplets

Author 1: Kohei Arai

Methods for size distribution estimation and rainfall type discrimination with estimated phase function using measured reflected laser light by rain droplet are proposed. Preliminary experiments are conducted with Laser ranging instrument and spectral radiometer for estimation of size distribution and rainfall type discrimination as well as phase function of scattering… Read full abstract & cite →

Data Hiding Method Replacing LSB of Hidden Portion for Secret Image with Run-Length Coded Image

Author 1: Kohei Arai

Data hiding method based on steganography improving secret image invisibility through replacing Least Significant Bit: LSB with run-length coded Image is proposed. Although, the proposed method is based on Discrete Wavelet Transformation: DWT, run-length coded secrete image is embedded in the LSB of the high frequency component before reconstruction of… Read full abstract & cite →
