These demos work best on Chrome and Chromium browsers. On other browser, some functionality may be slower or unavailable.

The JSM library source code which I used to generate the demos are available here and you may find the corresponding documentation here.

Estimation of Illuminants from Projections on the Planckian Locus

This demo aims at demonstrating the abilities of the PPL algorithm (see the corresponding publication) to detect different illuminants and estimate their chromaticities. It allows you to upload an image, define a white reference, and finally runs several algorithms and compare how well they behave.

Color Enhancement in the Wavelet Domain

This demo implements the algorithm introduced in the paper A Wavelet Perspective on Variational Perceptually-Inspired Color Enhancement published by E Provenzi and V Caselles. This algorithm performs color and contrast enhancement in the wavelet domain and this demo allows you to test it on your own images.

It performs many operations on images such as contrast and color modifications, filtering (morphological, bilateral, …). It also allows to visualize channels of different colorspaces.


Keypoint detector

Keypoint detection
This demo implements a Harris-Laplace keypoint detector as well as a main orientation section. It can be used a basis for descriptor extraction and matching.
