Graph Structure and Correlation Coefficient for Face Detection

Eimad Abusham · Sohar University Journal of Engineering and Information Technology Innovations · 2025 · 10.69983/sujeiti/115

… and aging. A novel approach to face detection is described in this paper using Local Graph Structure and Correlation Coefficient (LGS-CC). Through LGS-CC, texture information is enhanced by considering both texture and local shape, rather than relying solely on grayscale information. The proposed method has been shown …

Orbital solitary fibrous tumor: A clinicopathologic correlation and review of literature

Mohammad Javed Ali, Santosh G Honavar, Milind N Naik et al. · Oman Journal of Ophthalmology · 2011 · 10.4103/0974-620x.91274

Orbital solitary fibrous tumor (SFT) is a rare tumor originating from the mesenchyme. Initially described in the pleura and subsequently in other mesenchymal structures, orbit continues to be one of the uncommon extrapleural sites. The diagnosis of orbital SFT cannot be made with certainty on clinical or radiological e …
