Photo Color Adjustment, Enhancement and Correction

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Master's Thesis
Photo Color Adjustment, Enhancement and Correction
Thesis guide: Marcus Hoverby, Révolte Development AB, marcus@revolte.se
Research fields: Graphics algorithms and Usability


Background
The photo editors of today (e.g. Adobe Photoshop) have advanced photo correction capabilites, but they are very hard to learn to use for ordinary users. Révolte Development AB is building a photo editing
application that is easy to use and at the same time powerful for more advanced users.


Objective
The thesis is divided in two parts/research fields and has two objectives:
1. Graphic algorithms: To find algorithms to adjust, enhance and correct the colors of photo in different ways.
2. Usability: Investigate the need for photo adjustment for beginners and advanced users and design an easy-to-use user interface for this purpose.


Content
Photo correction algorithms
- Changing luminance and color intensity (using more advanced algorithms than brightness/saturation)
- Color corrections (compensating for too much yellow/blue/...) in hightlights/shadows
- Changing tone of the photo (warming filter/cooling filter/etc)
- Auto correction of a photo (histogram equalization, auto levels, auto color, etc)
- Histogram correction and curves
- etc

We would like to underline that parts of the research area color correction at first glance may seem obvious. But if you care about fine-tuning photos you will discover that there are lots of possibilities; For example the brightness of a photo can be changed in at least 10 different ways with different results.



About the company
Révolte Development is a is building a photo application similar to Adobe Photoshop.
The company was founded in 2002 and has since then had about 10 master's thesis students in different areas.

Kommentar:
Vi kommer under våren inte att ha möjlighet att på heltid ha exjobbare i våra lokaler, så exjobbet kommer till stor del ske på distans. Vi har tidigare haft några exjobbare som gjort exjobb på distans (framförallt från Uppsala) och det har fungerat bra.
