A continuous depth function is generated from the minimum depth to the maximum depth.

Tread depth means the depth of the principal grooves.

A predetermined maximum depth and a predetermined minimum depth are set.

The second depth is less than the first depth.

The input depth map comprises input depth samples and the output depth map comprising output depth samples, each depth sample having a respective depth value.

A depth of above, a depth of below; a depth of east, a depth of west; a depth of north, a depth of south.

A depth of above, a depth of below, A depth of east, a depth of west.

The second depth is greater than the first depth.

The depth map (DM) comprises depth indication values.

The first depth (d1) and the second depth (d2) are different.

A computation unit uses the depth predicted images to encode the depth images, thereby generating a depth stream.

A depth-map conversion unit (600) for converting an input depth map into an output depth map is disclosed.

Disclosed are a depth image encoding method capable of effectively coding a depth image and a depth image decoding method capable of decoding the coded depth image.

The invention includes analysing time versus depth data and generating velocity versus depth data and generating velocity versus depth function.

The charts may include: depth versus ethane/methane (fig. 3); depth versus δ13C per mil; and depth versus δ13C and gas show.
