Introduction #

Released 2019-09-13 ·Nicolai Häni, Pravakar Roy, Volkan Isler

The authors of the MinneApple: A Benchmark Dataset for Apple Detection and Segmentation introduce claim the need for advancing the current state-of-the-art in fruit detection, segmentation, and counting, particularly within orchard environments. This aim is pursued by offering an extensive collection of high-resolution images captured in orchards, complemented by human-generated annotations for the fruits present on the trees. The dataset serves a dual purpose, addressing two distinct subproblems integral to the broader challenge of yield estimation. Accurate fruit detection is essential for yield estimation, with the added complexity of clustered fruits necessitating a separate counting algorithm in most instances. Notably, apple objects are delineated with polygon masks, facilitating precise object detection, localization, and segmentation. Furthermore, the dataset includes data suitable for patch-based counting of clustered fruits, encompassing over 40,000 annotated object instances distributed across 1,000 images.

The data collection process primarily involves the capture of video footage from various sections of the orchard. A standard Samsung Galaxy S4 cell phone was employed for this purpose. During data acquisition, the camera was oriented horizontally, focusing on a single side of a tree row. Subsequently, individual images were extracted from these video sequences.

Summary #

MinneApple: A Benchmark Dataset for Apple Detection and Segmentation is a dataset for instance segmentation, semantic segmentation, object detection, and counting tasks. It is used in the agricultural industry.

The dataset consists of 69982 images with 23065 labeled objects belonging to 1 single class (apple).

Images in the MinneApple dataset have pixel-level instance segmentation annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation (only one mask for every class) or object detection (bounding boxes for every object) tasks. There are 69312 (99% of the total) unlabeled images (i.e. without annotations). There are 5 splits in the dataset: counting-train (64595 images), counting-val (3395 images), counting-test (991 images), detection-train (670 images), and detection-test (331 images). The dataset was released in 2019 by the University of Minnesota Robotic Sensor Network Laboratory.
