Monitoring Forest Loss in ALOS/PALSAR Time-Series with Superpixels

Remote Sensing, 2019
We present a flexible methodology to identify forest loss in synthetic aperture radar (SAR) L-band ALOS/PALSAR images. Instead of single pixel analysis, we generate spatial segments (i.e., superpixels) based on local image statistics to track homogeneous
