Students of the HAS University of Applied Sciences in Den Bosch have investigated the diligence of automatic image recognition based on earpiece picture . Bruce Schoelitsz report on behalf of the team of students about the undertaking in the framework of PPS ' Weet wat er Leeft ' ( sleep together what ’s life story ) at Glastuinbouw Nederland .
In the first study , having several species in one photo proved to be a foxy position . This was solved in field of study 2 by strategical analytic thinking . From September forward , new scholar project will begin in which the prediction exemplar for recognizing species will be condition further to square up whether the quality can be improved further .
The first study showed that the quarry coinage ( nursery whitefly , tobacco trips , green peach aphid , the predatory mites Montdo and Swirskii , and the parasitic wasp Aphidius colemani ) can be recognize with reflex image acknowledgment , but that it becomes more difficult if several species are on the photo at the same time . Of these species , trip were recognise least well , probably because of their lowly size of it .
In the second field , which was partially a follow - up of the first study , the problem of multiple species in one exposure was figure out by analyzing the photos in a strategical personal manner . As a result , more details are visible , and species are recognized considerably well .
paradigm recognition program more consistentIn plus , a portable lamp design by the students themselves was tested . The phone can be attached to the lamp in such a direction that there is no direct reflection in the television camera , and the entire gum trap can be photograph at once . The effect of the lamp is that the exposure is always the same , regardless of the light consideration in the nursery . Trips and whitefly , in special , were better pick out as a consequence , and the trope realization program play more consistently when the lamp was used . This means that the results on different days and with different light conditions in the greenhouse were sound as well as comparable .
The accuracy of paradigm realization without the lamp , on the other hand , differed greatly between dissimilar days , as a final result of which , for example , it may come along that there is much more whitefly present , while this is not the case . The lamp , therefore , really adds value to the students ' own anticipation model with all specie .
Other gum trapsFrom September onwards , new student project will start in which the prediction fashion model for recognizing species will be trained more to determine whether the lineament can be better further . For deterrent example , it will be look into whether very elaborate photographs with special television camera / scanner can be used and can improve range of a function acknowledgment . Furthermore , it will be investigate how well the insects are recognized when they are catch in other glue traps , with different color and wet glue or else of dry glue . But also to what extent accurate trends can be set . Within this trial , the first comparability with other techniques , such as eDNA , is also made .
This enquiry was carried out by Maxim Lisi , Marith Mol , Ella Ruizendaal , Corné van der Spek , Marijn de Waard , Jorn Walravens , Henk Heijmen , Berkay Helvaci and Robbert - Jan Seeleman .
