On-tree mango instance segmentation dataset

Dataset created for on-tree mango fruit detection and segmentation as a part of mango fruit size estimation study. Image datasets were prepared for training of Convolutional Neural Network (CNN) based instance segmentation model and annotated using VGG Image Annotation tool (Dutta & Zisserman 2019) with polygon region annotation. Two folders contain cropped images and COCO style JSON annotation files and randomly separated into training and test image sets. Images were taken at nighttime with the use of artificial light (LED light panel), using Azure Kinect RGB-D camera and Basler ace acA2440-75uc RGB camera.Datasets contain images from Honey Gold and Keitt mango cultivars and folders are organized as:Folder 1 (individual-mango-snips) - contains tiled-images and annotation file - A total of 542 (train + test) tiled images of 640 x 540 pixels.Folder 2 (tiled-images) - individual-mango-snips - Total 1200 (train + test) snips of variable dimensions (<150 pixels)For anyone intended to use the dataset for their research purpose, please cite following related journal paper:Neupane, C.; Koirala, A.; Walsh, K.B.

本数据集专为芒果果实挂树检测与分割任务构建，系芒果果实尺寸估算研究的组成部分。本图像数据集用于训练基于卷积神经网络（Convolutional Neural Network, CNN）的实例分割模型，采用VGG图像标注工具（VGG Image Annotation Tool，Dutta与Zisserman，2019）完成多边形区域标注。
数据集包含两个文件夹，分别存储裁剪图像与COCO风格JSON标注文件，并已随机划分为训练集与测试集。
图像均于夜间借助人工光源（LED灯板）拍摄，采集设备为Azure Kinect RGB-D相机与Basler ace acA2440-75uc RGB相机。
数据集涵盖Honey Gold与Keitt两个芒果品种，文件夹结构如下：
文件夹1（individual-mango-snips）：存储分块图像与标注文件，共包含542张（训练集与测试集）分辨率为640×540像素的分块图像。
文件夹2（tiled-images）内含individual-mango-snips目录，共包含1200张（训练集与测试集）尺寸可变（小于150像素）的图像片段。
