SC - powerful image rendering

Useful tool for rendering and outputting information rich images

Description

SC is a useful function for displaying rich image data, of use to anyone wishing to visualize and save 2D data in ways beyond that which MATLAB built-in functions allow.

This function can be used in place of IMAGE, IMAGESC and IMSHOW, but does so much more. It is fast and displays images as they should be - correct aspect ratio, integer magnification, no axes. In addition, it can return the image as an output variable - useful for saving to disk, texture mapping surfaces, and post-rendering manipulation such as overlaying/combining two or more images.

All the MATLAB built-in colormaps are implemented, but without MATLAB's nasty discretization artifacts. Plus, there are many new colormaps which are helpful for viewing more complex data, such as optic flow, likelihoods over images, difference images, segmentations, stereo image pairs (as anaglyphs) and edge-maps with orientation. It also accepts user defined linear and non-linear colormaps.

SC comes with a complete demo, to help you get the most out of it. It doesn't require that you have any toolboxes, either.

• MATLAB release: MATLAB 7.0.1 (R14SP1)

This is a pretty good package. I was just about to resort to either Zedgraph or Python to make some really pretty contour graphs (gotta pull out all the stops to get more funding. =P ), and ran across this. Very nice, and easy to use. The demo is a neat feature.

best viewing code ever

Excellent package, saved my day! Great support too! Highly recommended...

Finally found a relatively simple tool for overlaying some deformation maps on a binary image.
Took me about half an hour to get it to do what I was hoping it would (and this was helped due one of the examples in the demo).

Thanks very much for making this available!

It's great.

Perfect. I used it to get around the fact that Matlab only allows one colormap per figure axis, and with some trial and error I even got the colorbar I wanted to show up. Great work Oliver.

Doesn't show subplot titles. Must use

set(get(gca, 'Title'), 'Visible', 'on'); as a workaround.

[C. Chaya]

Otherwise, an excellent job. would give it 4.5 stars if the rating system would let me.

[Oliver Woodford]

Removing the axes is a "feature" of the display side of this code. Unfortunately it does mean subplot titles and axes labels are hidden. This is something I've tried hard to avoid, but haven't found a way yet. You can use IMSHOW instead, but still get the benefits of SC, thus:
   imshow(sc(X, 'jet'));

[Oliver Woodford]

The problem with not displaying titles and axis labels has now been fixed, thanks to C. Chaya's suggestion.

Extremely well done: excellent documentation, very instructive online demo (look at its code: so clean and compact!), lots of boundary-condition checks and clever packing of lots of options into a decievingly-simple interface. Some of this submission's defaults should have been imagesc's as well (for example, auto preservation of aspect ratio & axes elimination, not to mention the discretization issues). I love it!

Nice

[Jun wan]

veri nice .bue i didn't try it

[Justin]

The autopreservation of aspect ratio (mentioned by http://www.mathworks.com/matlabcentral/fileexchange/authors/27420) is the only thing I don't like about sc If I have a very long narrow matrix, imagesc scales it to display it in a standard sized matlab window. sc on the other hand gives me an extremely long narrow window. If there's an easy way to disable this please let me know.

Otherwise it's great.

[Oliver Woodford]

Justin - if you prefer the image displaying properties of imagesc I suggest you use image(sc(X)). However, you then don't get the correct colorbar. If it's just the aspect ratio you don't like then call set(gca, 'DataAspectRatioMode', 'auto') after sc.

Helpful, thanks
