Counting objects is a learning task common to many applications, from video sourveillance surveillance to agriculture 4.0, not to mention studies in life-sciences and medicine. However, this task is typically performed manually by domain experts, becoming very demanding in terms of time and human resources. Also, this increases the chances of errors due to distraction or fatigue.

This use-case deals with an approach to automate recognition and counting of objects in images. Specifically, we frame the problem as a *semantic segmentation* task and we use the the c-Resunet network architecture, taking the Fluorescent Neuronal Cells dataset as a benchmark.

The material is organized into notebooks that cover every stage of a realistic data analysis pipeline. In particular, a great deal of attention is devoted to EDA both to expose the challenges of the dataset and to evaluate the results. Likewise, technical aspects of the fastai implementation are detailed.
