Introduction #
In the pursuit of accurate detection and recognition of fruits and vegetables, the authors of the Fruit Recognition dataset acknowledge the persistent challenges posed by the similarities between various fruit types and the complexities of real-world environments, including lighting and background variations.
The dataset consists of 44,406 fruit images gathered over a span of 6 months. These images were taken within our laboratory’s controlled environment under various conditions, as elaborated below. All images were captured against a clear background with a resolution of 320×258 pixels, using an HD Logitech webcam for photography.
In the current era, traditional bar code technology continues to be used in fruit shops and supermarkets for price and source traceback information. Managing individual bar codes for various fruit categories poses challenges for shopkeepers. The authors highlight the significance of machine learning-based algorithms in object detection and recognition, particularly in addressing the preference of customers to select fruits individually rather than opting for prepackaged ones.
The data collection process confronted various challenges, including lighting variations, pose changes, camera artefacts, and shadows. The authors employed the split-and-merge algorithm to remove image backgrounds. To ensure model robustness, the dataset incorporated images with diverse illumination conditions and captured artefacts, specular reflections, and shadows, akin to real-world scenarios in supermarkets and fruit shops. The dataset further enhanced realism by featuring images taken at different times and days. The authors encountered substantial diversity in image quality and lighting. Data samples displayed environmental variations, adding complexity to the dataset. The authors emphasize the importance of a substantial dataset for effective deep learning algorithm training, particularly in cases where fruits share colour and size similarities.
Note, that this is a newer version of the dataset and the actual number of images and their resolution differ from what was described in the paper.

Research PaperSummary #
Fruit Recognition Dataset is a dataset for a classification task. It is used in the food and retail industries.
The dataset consists of 44792 images with 0 labeled objects. There are no pre-defined train/val/test splits in the dataset. Alternatively, the dataset could be split into 15 fruit categories: apple (6161 images), kiwi (4292 images), mango (4154 images), guava (3138 images), banana (3027 images), orange (3012 images), pear (3012 images), peach (2629 images), pitaya (2501 images), plum (2298 images), tomatoes (2171 images), pomegranate (2167 images), carambola (2080 images), muskmelon (2078 images), and persimmon (2072 images). Additionally, some fruit images contain information about different fruit kinds in sub-category. The dataset was released in 2018 by the Karakoram International University, Pakistan, King Saud University, Saudi Arabia, University of Agder, Norway, and Taiz University, Yemen.
Here are the visualized examples for the classes:
