Introduction #

Released 2022-09-24 ·Tingting Yang, Suyin Zhou, Zhijie Huanget al.

Authors introduce the Flower component for classification task within The Tree Dataset of Urban Street, encompassing 2,275 high-resolution images distributed across 17 classes. With these comprehensive resources at your disposal, this subset empowers researchers and practitioners to delve deep into the detailed analysis of urban street greenery, offering a valuable resource for comprehensive instance segmentation studies. Automatic tree species identification can be used to realize autonomous street tree inventories and help people without botanical knowledge and experience to better understand the diversity and regionalization of different urban landscapes.

About Tree Dataset of Urban Street:

Annotations were performed in a fine-grained manner by using polygons (bitmap in supervisely) to outline individual objects. Authors assessed the performance of various vision algorithms on different classification and segmentation tasks, including tree species identification and instance segmentation.

The proposed dataset was designed to capture urban street trees with subtropical or temperate monsoon climates in China. Our data collection and annotation methods were carefully created to capture the high variability of street trees. From February to October 2022, tens of thousands of tree images were acquired with mobile devices, covering spring, summer, fall and winter in 10 cities.

Similar to Cityscapes (Cordts et al., 2016) (available on DatasetNinja) and ADE20K (Zhou et al., 2019) (available on DatasetNinja), authors divide each organ dataset into separate training (train), validation (val) and test (test) sets.

Summary #

Tree Dataset of Urban Street: Flower Classification is a dataset for a classification task. It is used in the environmental industry.

The dataset consists of 2275 images with 0 labeled objects. There are 3 splits in the dataset: train (1828 images), val (228 images), and test (219 images). Alternatively, the dataset could be split into 17 classification image sets: osmanthus_fragrans (182 images), styphnolobium_japonicum (174 images), aesculus_chinensis (172 images), albizia_julibrissin (169 images), camptotheca_acuminata (168 images), lagerstroemia_indica (167 images), koelreuteria_paniculata (150 images), nerium_oleander_l (146 images), prunus_persica (139 images), flowering_cherry (126 images), rhododendron_pulchrum (119 images), photinia_serratifolia (116 images), malushalliana (109 images), loropetalum_chinense_var._rubrum (105 images), magnolia_liliflora_desr (87 images), liriodendron_chinense (74 images), and nandina_domestica (72 images). The dataset was released in 2022 by the Zhejiang Agriculture and Forestry University.
