A Review on Image Processing and Fractal Analysis in Oral Potentially Malignant Disorders

Oral Diseases, EarlyView.
ABSTRACT Aim The clinical evaluation of patients with oral potentially malignant disorders is primarily based on physical examination and observable clinical features. Clinical photographs play a key role in patient monitoring and help identify signs that may indicate malignant transformation.

Multi-scale morphological image enhancement of chest radiographs by a hybrid scheme

Journal of Medical Signals and Sensors, 2015
Chest radiography is a common diagnostic imaging test, which contains an enormous amount of information about a patient. However, its interpretation is highly challenging.

Dynamic Effects of Public Expenditure: The Challenge of Multi‐Level Governance Systems

Public Budgeting &Finance, EarlyView.
ABSTRACT The public economy literature shows that dynamic effects of public expenditure vary across programs, giving governments incentives to allocate spending with precision. However, this may be difficult in multi‐level governance, where centrally funded expenditure is implemented locally.

Sound offset responses become highly informative in the auditory cortex

The Journal of Physiology, EarlyView.
Abstract figure legend Using large datasets of neural responses to diverse sounds recorded across four stages of the mouse auditory system (depicted and colour‐coded on the left), offset responses occurring after the termination of each sound (time window indicated by the orange shaded area superimposed with activity traces) were characterized and it ...

Image enhancement algorithm combining histogram equalization and bilateral filtering

Systems and Soft Computing
In the process of image acquisition, transmission, and storage, the image quality is often degraded due to a variety of unfavorable factors, resulting in information loss, which poses certain difficulties for subsequent image processing and analysis. How

Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

Journal of Petroleum Geology, Volume 49, Issue 3, Page 869-906, July 2026.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

Low Contrast Enhancement Algorithm for Color Image Using Pythagorean Fuzzy Sets With a Fusion of CLAHE and BPDHE Methods

IEEE Access
In the field of image processing, improving low-contrast images is essential for enhancing the visibility of features that may be hard to see due to slight intensity variations. This issue often arises with images captured in poor lighting or unfavorable
