Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM HAVING IMAGE PROCESSING PROGRAM STORED THEREON
Document Type and Number:
WIPO Patent Application WO/2019/193702
Kind Code:
A1
Abstract:
An image processing device 10 is provided with: a segmentation unit 21 for segmenting an input image 200 showing the result of observing an ocean surface region and a land surface region from overhead into ocean surface block images 211 and land surface block images 212 on the basis of a segmentation criterion 210; a first determination unit 22 for determining a binarization criterion 220 for the ocean surface block images 211 on the basis of a scattering model for electromagnetic waves in the ocean surface region; a second determination unit 23 for determining a binarization criterion 230 for the land surface block images 212 on the basis of the binarization criterion 220 and the positional relationship between the ocean surface block images and the land surface block images; and a generation unit 25 for generating a land mask image 250 by performing binarization processing of the input image 200 that is based on the binarization criterion 220 and the binarization criterion 230. As a result of this configuration, the present invention improves the accuracy in generating a land mask image for differentiating between an ocean surface region and a land surface region in remote sensing technology.
