Gloss paper in JOSA A

Great news! Our new paper on gloss evaluation has been accepted and will appear in the issue in September!

In June 2016, when I was visiting Prof. Luo’s lab at Zhejiang University, we decided to revisit gloss perception with new instrumentation (BRDF). It was fun collecting and making those gloss samples and conducting psychophysical experiments.

The motivation of this project is to overcome the spatiotemporal tradeoffs of modern cameras. Data is redundant. This is a ubiquitous phenomenon people have witnessed. On the other hand, sampling a full resolution image (with redundancy) takes longer time than sampling fewer pixels for a camera. Thus, a natural question is if we can save spatial resolution for higher imaging speed.

My most recent project works on 4D imaging. That’s to compress both spatial and temporal information into a single image.

Glint impression and diffuse coarseness

Looking into special surface effects: diffuse coarseness and glint impression

glint sample

How do human understand and distinguish sparking (glint) and graininess (coarseness).

We conducted a psychophysical experiment to model these two effects.

And if you compare the visual result with instrumental measurement, you will find one dimension is not enough to represent human response.

glint dimensions

We used multidimensional scaling to find the feasible dimensionality (2 dimensions are better and not redundant).

and then, if we represent the data into 2 dimensions, what is actually the principle axis, what is the adjunct axis. And what are the meanings of them?
