Abstract

In the current trend towards contactless recognition, palmprint biometrics has proven to be very effective due to its uniqueness, reliability, acceptability, non-intrusiveness and low cost of acquisition devices. Palmprint biometrics can be used in many situations by simply capturing the hand with the camera of a mobile device. However, its use in real-life situations adds a high variability to the capturing conditions, increasing the complexity of the recognition process and causing failure of many processing methods up to date. In this study, a deep-learning algorithm is proposed to detect the palmprint region of interest and rotating the image as needed for the subsequent feature extraction on it. For this purpose, a convolutional neural network (CNN) has been trained and evaluated with 2445 hand images from 6 different databases that cover diverse environmental conditions. Results show that this algorithm provides an averaged F 1-score of 89% in images with complex backgrounds, dim light or varied hand arrangements; and it correctly processes images in which users are wearing rings, something that traditional segmentation cannot handle. Some conditions such as hard shadowing remain very complex for this algorithm, but it could be highly improved by increasing the volume of training datasets.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-12-20:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 1.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 1 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.
