How good are your gradients?
I have been thinking a lot about my sketching habits lately. I have noticed I tend to draw, or shade-in really, lots of circles and squares. I love shading… getting the gradient just right. I get the same feeling when I am laying out a page in graphically… theres something about the minute adjustments and gut feelings I really love. So, when brainstorming about a new project for Computational Cameras drawing popped into my head.
What could I do to interact with a computer while drawing? Lost I’m sure, but I quickly got fixed on this idea of the computer analyzing and judging the smoothness of my gradients. For this first attempt I am just analyzing a still image under controlled circumstances (photoshop adjusted background). But in the future I want to expand this to analyze my shading at different angles and dynamically. THAT would be cool… like a computer assist.
This is what it does: Loads in a image, averages the pixels’ brightness in each row that are larger than a white threshold, then graphs (in pink) those averages on the side. Then you can see the image and the graph of your brightness gradient. yay
