Image Warping #58

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

The idea would be to input a source image and a distort map, and to get 
back a distorted image as output.
The input map would consist of a set of points locations with coresponding 
new location, or motion vectors. 

With computed distort map, many filters can be derived from that base, 
like swirl, spherize, water effect etc.
With manually or indirectly computed distort map, effects like morphing 
could be achieved.

Hi,

I've implemented the 1 of the filters requested (water), are you interested in 
the
others from the web page being added?

I've refactored the code and committed it as WaterWave class.

Not really sure. Coding style of the Water.cs was quite poor (code, 
documentation, 
optimization, features of the class).

By the way. The ticket actually asks a bit different. Instead of creating 
separate 
class for each effect, it is required to create single image processing 
routine, 
which takes an image and map of displacements (motion vectors). This will allow 
creating any type of effect by user (user just calculates the map and the rest 
is 
done by image processing routine). But, on another hand, making specially 
designed 
effects is also nice, since it allows to have things like interpolation, etc. 
(something, which is custom for certain effect).

Added ImageWarp image processing filter, which sets pixels in destination image 
to 
values from source image taken with specified offset.

Committed in revision 1201. Will be released in version 2.1.2.
