Temporal Mango fruit Dataset

The dataset consists of images of mango trees of four different cultivars (Mallika, Raspuri, Arka Arun, and Malgoa), obtained with the main camera of a mobile phone (Oneplus A5000, dual camera (16 MP, f/1.7, 24mm wide, 20 MP, f/2.6, 36mm standard) under natural daylight conditions with an image resolution of 1920*1080 pixels. Data was collected for 5 months temporally in the interval of 7 days for the first 3 months. Then the frequency of data collection is increased for the subsequent two months based on fruit maturity. 800 images per day are captured.
The images were captured in two sessions, namely morning and evening, which is aligned with the direction of the sunlight. Further, we have captured these trees from distances of 2 and 3 meters, respectively.
The selected trees from the orchid vary from 15-20 years of age. The trees range between 7-8 feet high from the
surface. The size of each acquired image ranges between 7-8 MB. The dataset accounts for 21000 images altogether.
In a day, the dataset is collected in two sessions: session 1 was between 9:30 am and 10:00 am and session 2 between
2:30 pm and 3:00 pm from north-east and south-west directions, respectively.
Therefore, the acquired images cover the contour of a tree. However, top and bottom views are exempted from the acquisition. The
dataset was collected throughout a season for five months.

本数据集收录了四种不同品种（Mallika、Raspuri、Arka Arun及Malgoa）的芒果树图像，图像由一部智能手机（Oneplus A5000，双摄像头配置，主摄像头为16 MP，光圈f/1.7，等效焦距24mm，副摄像头为20 MP，光圈f/2.6，等效焦距36mm）在自然光照条件下拍摄，图像分辨率为1920*1080像素。数据收集时间跨越5个月，前3个月每7天收集一次数据。随后，根据果实成熟度，数据收集的频率在接下来的两个月内进行了提升，每日采集800张图像。图像拍摄分为两个时段，即上午和傍晚，与日光方向保持一致。此外，我们还从2米和3米的距离分别拍摄了这些树木。所选树木的年龄介于15至20年之间，树高在2.4至2.5米之间。每张图像的大小介于7至8兆字节。整个数据集总计包含21000张图像。每日数据收集分为两个时段：第一时段为上午9:30至10:00，第二时段为下午2:30至3:00，分别从东北和西南方向进行拍摄。因此，所获得的图像覆盖了树木的轮廓。然而，顶部和底部视角的图像未被收录。数据集在整个季节的五个月内进行了收集。
