IR Frequency Region: Fingerprint Region01:03

IR Frequency Region: Fingerprint Region

1.4K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

Muscles of the Forearm that Move the Hand and Fingers

1.7K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Extraction: Advanced Methods

644
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Area of Science:

  • Biometrics
  • Computer Vision
  • Pattern Recognition

Background:

  • Palmprint recognition is a user-friendly biometric technology due to its non-invasive and hygienic properties.
  • Current deep-learning methods for palmprint recognition require extensive labeled data, which is often difficult to obtain.
  • Limited availability of palmprint samples hinders the effectiveness of existing deep-learning-based recognition systems.

Purpose of the Study:

  • To propose a novel heuristic palmprint recognition method that does not require training samples.
  • To address the challenge of limited data availability in palmprint recognition systems.
  • To develop an effective palmprint recognition technique that utilizes inherent palmprint features.

Main Methods:

  • Extraction of three inherent palmprint features: texture, gradient, and direction.
  • Encoding these features into triple-type feature codes.
  • Representation using block-wise histograms of feature codes to form triple feature descriptors.
  • Weighted matching-score level fusion for similarity calculation and recognition.

Main Results:

  • The proposed heuristic method demonstrates promising effectiveness in palmprint recognition.
  • The method achieves good performance without the need for any training samples.
  • Experimental results on three widely used palmprint databases validate the method's efficacy.

Conclusions:

  • The developed heuristic palmprint recognition method is effective, particularly in scenarios with limited data.
  • The triple-type feature extraction and fusion strategy provide a robust approach to palmprint identification.
  • This method offers a viable alternative to data-intensive deep-learning techniques for palmprint recognition.
