Değiştirilmiş Ayrık Haar Dalgacık Dönüşümü ile Yeni Bir Histogram Eşitleme Yöntemi
Bulut, Faruk (Mühendislik Bilimleri ve Tasarım Dergisi, 2022)Histogram eşitleme dijital görüntülerin kontrastını artırmak için kullanılan yöntemlerden biridir. İdeal histogram eşitleme yöntemlerinde, girdi ve çıktı arasındaki görüntü benzerliğini koruyarak histogramdaki dağılımları ... -
Iterative histogram equalization using discrete wavelet transform in low-dynamic range
Bulut, Faruk; Ince, Ibrahim Furkan (SPIE, 2023)A progressive histogram equalization (HE) and contrast enhancement method is proposed in the frequency domain. This method has an iterative structure based on the 6-sigma rule in the low-dynamic range using discrete wavelet ... -
Low dynamic range discrete cosine transform (LDR-DCT) for high-performance JPEG image compression
Ince, Ibrahim Furkan; Bulut, Faruk; Kilic, Ilker; Yildirim, Mustafa Eren; Ince, Omer Faruk (Springer Science and Business Media Deutschland GmbH, 2022)In mathematical theory, the discrete cosine transform (DCT) is a lossless orthogonal transformation method which means it outputs exactly the same values of the input after the inverse transformation. However, this is ... -
Low Dynamic Range Histogram Equalization (LDR-HE) Via Quantized Haar Wavelet Transform
Bulut, Faruk (Springer, 2021)Conventional contrast enhancement methods stretch histogram bins to provide a uniform distribution. However, they also stretch the existing natural noises which cause abnormal distributions and annoying artifacts. Histogram ... -
Performance boosting of image matching-based iris recognition systems using deformable circular hollow kernels and uniform histogram fusion images
Bulut, Faruk; Shehu, Harisu Abdullahi; Ince, Ibrahim Furkan (SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS, 2022)Identification of people using different biometric data is becoming more important in network society. Biometrics include voice, ears, palms, fingerprints, faces, iris, retina, and hand shapes. Among these features, iris ...
