We are looking for a highly motivated Master student for a research internship.
- Keywords: Image manipulation, Color grading, Point clouds, Computer Graphics
- Advisor: David Vanderhaeghe, Nicolas Mellado
- Location: Laboratoire IRIT, STORM research team, Université Paul Sabatier – Toulouse
- Duration: from February/March 2018, 5-7 months
The internship will take place in the IRIT laboratory, on the Université Paul Sabatier, campus of Toulouse. The recruited intern will be a full member of the research team, integrated with other team members, PhD students and permanent researches. He/she will participate to working groups, scientific seminars and other activities of our group.
Professional pictures present strong color ambiances influencing the style and the mood of the image. These ambiances are usually set at the capture stage using light spots of different colors or adjusted at the compositing stage.
Professional softwares (such as Photoshop) provide different tools to change the color temperature or shift color hues. These filters are applied globally on the image.
Following recent works [1,2] and preliminary investigations, the rgb point cloud (fig 1 right) corresponding to an image depicts structures that can enable image manipulation.
The purpose of this internship is to analyze the rgb point cloud to extract meaningful geometrical structures. Using this structure, the student has to propose tool to edit the image.
A preliminary result is presented below
