COMPRESSION OF EARTH OBSERVATION SATELLITE IMAGES |
摘要 |
<p>The invention relates to a method of acquiring, compressing and transmitting satellite images, characterized in that in a systematic manner: an image is acquired (101); (102) said image is processed by an image preprocessing step providing a value characteristic of the image and an image preprocessed by recognizing predetermined natural objects in the acquired image and replacing said natural objects by standard objects; said characteristic value is compared (103) with a table of values, each value of which is associated with a compression algorithm; the compression algorithm corresponding to said characteristic value is implemented (104) by compression means for compressing said image; said compressed image is transmitted (105) to a remote image reception device by transmission means.</p> |
