Method of coding artifacts reduction

A method to reduce coding artifacts within a discrete decoded picture, said method comprising the steps of:

• spatial and/or temporal filtering with respective filter characteristics dependent on an image quality value;
• wherein said image quality value is determined based on a user selection;
• wherein the temporal filter operation decreases with an increasing image quality value;
• wherein the temporal filter operation is realized with a blending filter applied to an entire frame which determines a new frame as a weighted sum of a predicted frame and an actual frame, which weighting is dependent on said image quality value and a difference of the actual frame with the predicted frame, and
• wherein said predicted frame is determined on basis of a motion compensation of a previously determined new frame.

A method to reduce coding artifacts within a discrete decoded picture, said method comprising the steps of:

• spatial and/or temporal filtering with respective filter characteristics dependent on an image quality value,
• wherein said image quality value is determined based on a user selection and wherein said spatial filtering includes a deblocking filtering, and
• wherein the deblocking filter operation decreases with an increasing image quality value and
• wherein the deblocking filtering chooses an activity-dependent weighting function for a pixel to be filtered according to a image quality value and
• wherein the activity of both blocks to which a common border of said pixel belongs is considered.

A method to reduce coding artifacts within a discrete decoded picture, said method comprising the steps of:

• spatial and/or temporal filtering with respective filter characteristics dependent on an image quality value,
• wherein said spatial filtering includes a deringing filtering,
• wherein said deringing filter operation decreases with an increasing image quality value and
• wherein said deringing filtering chooses a deringing mask dependent on said image quality value, and
• wherein said image quality value is determined based on a user selection.

A device for picture processing, comprising:

• spatial and/or temporal filters with respective filter characteristics dependent on an image quality value,
• wherein said image quality value is determined based on a user selection;
• wherein the temporal filter operation decreases with an increasing image quality value;
• wherein the temporal filter operation is realized with a blending filter applied to an entire frame which determines a new frame as a weighted sum of a predicted frame and an actual frame, which weighting is dependent on said image quality value and a difference of the actual frame with the predicted frame.
