• Brightness preserving fuzzy dynamic histogram equalization 

      Sarrafzadeh, Hossein; Rezazadeh, Fatemeh; Shanbehzadeh, Jamshid (Newswood Ltd., 2013)
      Abstract—Image enhancement is a fundamental step of image processing and machine vision to improve the quality of an image for a specific application. Histogram equalization is an attractive and commonly-employed image ...
    • Development of unified and dynamic geometric framework for modelling plant leaf spots 

      Alshadli, Duaa; Borna, Kambiz; Lador, Cesar (2020-11)
      The use of computer vision and image processing techniques have proven to be effective in detecting and classifying plant diseases from symptoms, such as leaf spots or mosaic leaf patterns caused by pathogens. To identify ...
    • Document image noises and removal methods 

      Farahmand, Atena; Sarrafzadeh, Hossein; Shanbehzadeh, Jamshid (Newswood Ltd., 2013)
      Document images may be contaminated with noise during transmission, scanning or conversion to digital form. We can categorize noises by identifying their features and can search for similar patterns in a document image to ...
    • Fuzzy C-means based on automated variable feature weighting 

      Nazari, Mousa; Shanbehzadeh, Jamshid; Sarrafzadeh, Hossein (Newswood Ltd., 2013)
      Fuzzy C-means (FCM) is a powerful clustering algorithm and has been introduced to overcome the crisp definition of similarity and clusters. FCM ignores the importance of features in the clustering process. This affects its ...
    • An overview of different binary methods for documents based on their features 

      Fazeli, Fatemeh; Sarrafzadeh, Hossein; Shanbehzadeh, Jamshid (Newswood Ltd., 2013)
      This paper surveys binarization of document images. The main role of binarization is dimension and noise reduction. Binarization is one of the most important steps in preprocessing of document image understanding and ...
    • Skew detection of scanned document images 

      Rezaei, , Sepideh Barekat; Sarrafzadeh, Hossein; Shanbehzadeh, Jamshid (Newswood Ltd., 2013)
      Skewing of the scanned image is an inevitable process and its detection is an important issue for document recognition systems. The skew of the scanned document image specifies the deviation of the text lines from the ...
