Abstract
Method for image portion retrieval and display for the relatively large scale of imagery data onto comparatively small size of display is proposed. The method is suitable to the data compression methods based on block coding. Through experiments with satellite imagery data, it is found that the proposed method is useful for the display onto small sized screen such as mobile phone display and so on.
Highlights
There is a strong demand for displaying remote sensing satellite images onto mobile phone screen
The pixel size of mobile phone is less than one million pixels while that of remote sensing satellite images is more than 10 million pixels, in general
Data compression is desirable to reduce the time required for transmission and receiving relatively large size of HDTV images and remote sensing satellite images
Summary
There is a strong demand for displaying remote sensing satellite images onto mobile phone screen. Pixel size of the remote sensing satellite images, in general, is much greater than that of mobile phone screen. Scrolling or roaming of the displayed HDTV image or remote sensing satellite image on the mobile phone screen is required. Data compression is desirable to reduce the time required for transmission and receiving relatively large size of HDTV images and remote sensing satellite images. Image portion retrieval and display method proposed here is to search the most preferable portion of images by block by block. The proposed search and display method is suitable to block coding of data compression method. The following section describes proposed method for image portion retrieval and display method followed by some examples of image portion retrievals and display onto mobile phone screen.
