Abstract
Official abstract text for this publication.
A method of acquiring, compressing and transmitting satellite images, characterized in that in a systematic manner: an image is acquired ( 101 ); ( 102 ) the 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 the natural objects by standard objects; the 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 the characteristic value is implemented ( 104 ) by compression elements for compressing the image; the compressed image is transmitted ( 105 ) to a remote image reception device by transmission elements.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for acquisition, processing, compression and transmission of Earth observation satellite images, comprising: acquiring an image, named acquired image, by an instrument carried by a satellite, processing said acquired image by an image preprocessing step adapted to provide a preprocessed image and at least one numerical value, referred to as the characteristic value of said acquired image, representative of a content of said image, said prepr…
