| Summary: | Penyeragaman Histogram Sejagat (Global Histogram Equalization (GHE)) adalah salah
satu kaedah penyerlahan imej yang terkenal. GHE masih mempunyai batasan walaupun ia
mudah dan dikenali. Oleh kerana itu, terdapat dua kaedah baru yang berdasarkan Penyeragaman
Histogram (Histogram Equalization (HE)) telah dicadangkan iaitu Penyeragaman Histogram
Dinamik Kecerahan Berkekalan (Brightness Preserving Dynamic Histogram Equalization
(BPDHE)) dan Penyeragaman Histogram Bertindih Blok Berbilang Aras (Multi-Levels
Block Overlapped Histogram Equalization (MLBOHE)).
Global Histogram Equalization (GHE) is one of the well-known image enhancement methods.
Despite of its simplicity and popularity, GHE still has limitations. Therefore, in this work,
two novel Histogram Equalization (HE) based methods have been proposed, which are Brightness
Preserving Dynamic Histogram Equalization (BPDHE) and Multi-Levels Block Overlapped
Histogram Equalization (MLBOHE). |
