    • Color image denoising and contrast enhancement in contourlet domain 

      Melkamu, H. Asmare; Vijanth, S. Asirvadam; Lila Iznita (Universiti Malaysia Perlis, 2009-10-11)
      A degraded image mainly has dark shadows, over bright regions and blurred details. These images are usually affected by noise. This paper proposes a method which tries to avoid this problems. Image denoised image is further ...

    • Combination of local and dark stretching for Ziehl-Neelsen TB bacilli slide images in tissue and sputum samples 

      Nurul Wahidah, M. F.; Norsima Nazirah, Sidek; Mohd Yusoff, Mashor, Prof. Dr.; Md Noor, S. S. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      Tuberculosis is an infectious and dangerous disease which can spread through the air when the infected person coughed, sneezed or spited. Sputum and tissue sample analysis is a common method for extra-pulmonary and pulmonary ...

    • Contrast enhancement for medical images based on histogram equalization followed by median filter 

      Jagatheeswari, P.; Suresh Kumar, S.; Rajaram, M. (Universiti Malaysia Perlis, 2009-10-11)
      The goal of image enhancement technique is to improve a characteristics or quality of an image, such that the resulting image is better than the original image. Histogram equalization (HE) is widely used for contrast ...

    • Enhancement techniques for tuberculosis slide images: A review 

      Nurul Wahidah, M. F.; Mohd Yusoff, Mashor, Prof. Madya. Dr.; Siti Salwa, Md Noor (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      Tuberculosis (TB) is a very hazardous disease caused by infection of germ Mycobacterium tuberculosis that can cause death to the patient. TB can spread like common flu such as through air or direct body fluid connection. ...

    • Image enhancement and segmentation using dark stretching technique for Plasmodium Falciparum for thick blood smear 

      N. S. M. M., Hanif; Mohd Yusof, Mashor, Prof. Dr.; Zeehaida, Mohamed, Dr. (The Institute of Electrical and Electronics Engineers (IEEE), 2011-03-04)
      This paper present the results of applying dark stretching technique to enhance and segment the Plasmodium Falciparum based on thick blood smear images. Image enhancement is the process to improve the quality (clarity) of ...

    • Image enhancement technique for bone marrow 

      Nurul Hazwani, Abd. Halim; Mohd Yusoff, Mashor, Prof. Dr.; H., Rosline (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      This paper presents a study on image enhancement technique for improving the features of blasts in acute leukemia bone marrow samples. The morphological features in bone marrow images could be improved if poor contrast ...

    • Image enhancement technique using partial contrast stretching on abnormal Bone Marrow images for Leukemia screening 

      E. U., Francis; Mohd Yusoff, Mashor, Prof. Dr.; Azian Azamimi, Abdullah; Roseline, Hassan, Dr. (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      Image Enhancement is a very useful pre-processing method that is implemented on biomedical images to eliminate poor contrast, thus improve interpretability for human’s vision. In Leukemia, the Bone Marrow generally ...

    • Image enhancement techniques for thalassaemia images using bright, dark and partial contrast stretching method 

      N. Z. N., Rashid; Mohd Yusoff, Mashor, Prof. Dr.; Rosline, Hassan, Dr. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      Image enhancement techniques are used as pre-processing tools in digital image processing. The purpose of this technique is to improve the quality of image without knowledge about the source of degradation. The image results ...
