Resumen: The quantification of microplastics is a needed task to monitor its evolution and model its behavior.However, it isa time demanding task traditionally performed using expensive equipment. In this paper, an architecture basedon deep learning networks is presented with the aim of automatically count and classify microplastic particles inthe range of 1–5 mm from pictures taken with a digital camera or a mobile phone with a resolution of 16 millionpixels or higher. The proposed architecture comprises afirst stage, implemented with the U-Net neural network,in charge of making the segmentation of the particles in the image. After the different particles have been iso-lated, a second stage based on the VGG16 neural network classifies them into three types: fragments, pelletsand lines. These threetypeshave been selected for beingthe mostcommon in the range sizeunder consideration.The experimentalevaluation was carried out usingimages taken with two digitalcameras and one mobilephone.The particles used in experiments correspond to samples collected on the beach of Playa del Poris in Tenerife Is-land, Spain, (28° 09′51′′N, 16° 25′54′′W) in August 2018. A Jaccard index value of 0.8 is achieved in the exper-iments of particles segmentation and an accuracy of 98.11% is obtained in the classification of the microplasticparticles. The proposedarchitecture is remarkablefaster than a similar previously published system based on tra-ditional computer vision techniques.
