WoodChip-MC: Wood Chip Image Dataset for Moisture Content Prediction

The dataset WoodChip-MC consists of 1,600 RGB images of wood chips collected from two different sources. The dataset has images from 2 sources: each source has 10 moisture levels. One of the sources is subdivided into two batches. These images were acquired by an industrial camera (Hotpet 8MP USB Industrial Camera with Sony IMX179 Sensor) while keeping the wood chips in an aluminum container. The images were manually labeled through the oven-drying process. The wet wood chips were kept in an oven dryer (set at 105 ◦C) for 24 hours, and then moisture content was calculated from the weight difference. 

The dataset, at the time of publication, is the largest publicly available data for wood chip moisture content determination through computer vision. With the WoodChip-MC dataset, a performance benchmark of deep learning models has been developed for moisture content class prediction. Detailed model benchmarking and performance results are given in an accompanying journal paper: Rahman, A., Street, J., Wooten, J., Marufuzzaman, M., Gude, V. G., Buchanan, R., & Wang, H. (2025).
