Cocoa (see figures) is the basic ingredient to produce chocolate. It is grown in many tropical countries like Ivory Coast, Ghana, and Ecuador. For market research, big chocolate companies need to know the overall acreage of cocoa and a rough estimation of annual yield to adjust their buying strategy accordingly. Today, this is done manually by sending experts into the field that regularly measure the size of cacao beans and estimate the area of cocoa plantations.
The aim of this project is to combine satellite images of the new ESA constellation Sentinel-2 and deep learning to segment cocoa planting sites in Africa and Latin America. What makes this task hard is the high similarity of cocoa and surrounding plants, often smallholder farms especially in Africa, and the inhomogeneous acquisition frequency due to frequent cloud coverage.
The candidate will develop a deep learning method and implement a software to segment cocoa at large scale.
