PhD in Computer Science

Thesis title : Image time series analysis involving spatial and temporal information

New constellations of satellites acquire images with a high spatial, spectral and temporal resolution around the world leading to Satellite Image Time Series (SITS). During my thesis, our objective is to analyse the image time serie in order to extract features that enrich the orginal data and perform an application, such as a classification, by maximazing the accuracy

Temporal stability

Spatio-temporal hand-crafted features extraction that measure the stabilty. The proposed method is based on a compression algorithm named Run Length Encoding.

Temporal stability code available on github
