Abstract

Ovaj rad implementira metodu semantičke segmentacije za detekciju grožđa u vinogradu predstavljenu u (Perez, Rodrigo, 2017). Za razliku od današnjih standarda umjetnih neuronskih mreža i dubokog učenja, ova metoda problemu pristupa konvencionalnijim metodama računalnog vida. Koristi se FRST algoritam za detekciju radijalno simetričnih točaka iz kojih se računaju vektori značajki HOG i LBP deskriptorima. Zatim se SVM klasifikatorom određuje koje točke pripadaju skupu grožđa te se grupiraju... More DBSCAN algoritmom. Rezultat metode je binarna maska koja označava područja fotografije u kojima je prisutno grožđe. Cilj je korištenje detekcije grožđa u svrhu smanjivanja izgubljenog materijala tijekom prskanja plodova u vinogradu, no ovaj rad samo demonstrira funkcionalnost. Less

Abstract (english)

This work implements a method of semantic segmentation for grape detection in the vineyard shown in (Perez, Rodrigo, 2017). Unlike today's standards of computer vision using artificial neural networks and deep learning, this method uses more conventional computer vision methods. The FRST algorithm for detecting points of radial symmetry is used from which feature vectors of HOG and LBP descriptors are computed. Then, the SVM classifier determines which points belong to a cluster of... More grapes and are grouped by the DBSCAN algorithm. The result of the method is a binary mask that indicates areas of images in which grapes are present. The aim is to use grape detection for the purposes of reducing waste while spraying in viticulture, but this work only demonstrates functionality of the method. Less
