A new portable sampler to monitor pollen at street level ...

20201101· The results showed that the pollen levels for birch and grass pollen can significantly differ from location to location and per time of day. Furthermore, the Pollensniffer measurements at street level showed that birch and grass pollen grains were detected 1 1/2 and 2–3 weeks, respectively, before detection at rooftop level. The street ...

Detection and Classification of Pollen Grain Microscope Images

been proposed for the task of pollen grain detection such as the ones used in [17]; however, the number of grains is between and objects. Furthermore, in [17] the authors proposed a system to recognize biological particles. The proposed system is composed of four stages: First, they detected locations or small regions containing interesting samples by using a feature finder ...

Realtime Pollen Detection by Intrinsic Protein ...

A prototype sensor was constructed using readily available materials and tested using multiple pollen grains (2030) with satisfactory results. Additional experimental tests to establish the singleparticle sensing characteristics of the sensor was successful with the detection of a single hibiscus pollen grain (20µm) noted. The results of the experiments showed that ultraviolet lightinduced ...
