    • Illumination and contrast correction strategy using bilateral filtering and binarization comparison 

      Wan Azani, Mustafa; Haniza, Yazid (Universiti Teknikal Malaysia Melaka, 2016)
      Illumination normalization and contrast variation on images areone of themost challenging tasks in the imageprocessing field. Normally, the degrade contrast imagesarecaused by pose, occlusion, illumination,and ...

    • Image quality assessment (IQA) using high-frequency and image variance (HFIV) for colour image 

      Li Chien, Tan; Haniza, Yazid; Yen Fook, Chong (IOP Publishing, 2019)
      Image quality is often lost during image acquisition, transmission, and compression. Therefore, image quality assessment (IQA) is crucial in image processing. Currently, image quality can be measured from the frequency ...
