Digital image contrast improvement techniques by multi-peak histogram divided

Phanthuna, Nattapong; ณัฐพงศ์ พันธุนะ; Cheevasuwit, Fusak; ฟูศักดิ์ ชีวสุวิทย์ (2020-03-05)

Currently competition in terms of resolution and contrast of photos from digital cameras are widely mentioned. The higher resolution the photos contain; the more details the picture has. This fact enables the more details ...
Fusion of multispectral and panchromatic image using improved PCA mergers with discrete wavelet based algorithms

Phanthuna, Nattapong; Cheevasuwit, Fusak (2017-10-19)

The data fusion is implement to take the survey data remotely from difference sources and have various looks to be combined to get a new agent. To get better quality of data, we will present a method of fusion by wavelet ...
SAR image segmentation via improving watershed algorithm with histogram enhancement

Phanthuna, Nattapong; ณัฐพงศ์ พันธุนะ; Cheevasuvit, Fusak; ฟูศักดิ์ ชีวสุวิทย์ (2020-01-31)

Since the details in quasi-homogeneous region will be degraded from a conventional global image enhancement methods such as histogram equalization. This degradation causes from the saturation of the gray levels in equalization ...
