Abstract
In order to achieve the aim of the invention, a method for the coding of a series of images is disclosed, whereby base information and additional information are determined for the series of images. Said images are coded by means of the base information and the additional information, whereby the additional information guarantees a progressive improvement in image quality.
Claims14
Method for coding a series of images,
- a) with base information and additional information being determined for the series of images using the following steps:
- (1) The base information is determined using a method for source coding, with residual error information being produced during the source coding, between the series of images and a coded series of images.
- (2) The additional information is generated for the gradual representation of residual error information, in that the residual error information is subdivided into frequency ranges and gradually scaled.
- b) with the series of images being coded using the base information and the additional information, with the additional information guaranteeing a progressive improvement in the coding quality.
Method according to one of the preceding claims, with the residual error information being determined from one image in the series of images and the quantized image in the series of images in an image area.
Method according to one of the preceding claims, with the residual error information being determined from one image in the series of images and the quantized image in the series of images in a transformation area.
Method according to one of the preceding claims, with the method for source coding being a standard image coding method.
Method according to one of the preceding claims, with the base information being taken into account when determining the additional information.
Method for decoding a series of images which were coded according to one of the preceding claims, with each image in the series of images being restored using the base information and the additional information.
Arrangement for coding a series of images, with a processor unit being provided which is set up such that
- a) base information and additional information are determined for the series of images using the following steps:
- (3) The base information is determined using a method for source coding, with residual error information resulting, during the source coding, between the series of images and a coded series of images.
- (4) The additional information is generated for the gradual representation of residual error information, in that the residual error information is subdivided into frequency ranges and gradually scaled.
- b) the series of images is coded using the base information and the additional information, with the additional information guaranteeing a progressive improvement in the coding quality.
Arrangement for decoding a series of images, with a processor unit being provided which is set up such that each image in the series of images can be restored using the base information and the additional information.
