    Hi, I'm working as a machine learning engineer from Egypt, and our company works with images, I have never found such effective and useful materials as your videos, thank you and may god bless you.

    I like your style of touching the basics when explaining advanced topics.

    Hi, i currently on trying CLAHE, but i really don't understand about how to calculate cliplimit and implement it on the histogram of sub-image. Can anyone explain?

    can u tell how we will do it if we parallelize this algorithm.

    how about manualy calculate clahe?

    Thank you for that video. I have a question regarding histopathological image: which is better to apply CLAHE or stain normalization?
    Also, should we do this CLAHE method and then do pixel normalization to convert them to fit [-1,1] or [0,1]?

    • @shivamsingh-fn8vz
      @shivamsingh-fn8vz 2 ปีที่แล้ว

      i think we should do CLAHE before pixel normalization since it will have bigger range to smooth thus saving more information

    informative video.. sir one doubt ,, for classifying road puddle: when i give road with shadows , my deep learning model mispredict it as road puddle.. can i use histogram equalisation to solve this?

    How do you determine the clip value for CLAHE? Is it arbitrary?

    • @DigitalSreeni
      @DigitalSreeni  4 ปีที่แล้ว +1

      Completely depends on the image, I would try 30 or 40 as a starting point.

    First of all thanks for the videos.
    what about if I need to work with a gray image?, how can I transform it in a LAB space

      I recorded a video for my work on the topic of color spaces. May be that clarifies your questions ... th-cam.com/video/kL4j-qGkTnY/w-d-xo.html

      @@DigitalSreeni Good night professor, Can I contact you?, I'm developing a code to search for small and faint objects (little point objects) among a pattern of objects (streak lines), but I'm new in this field of image processing, so I'd like some help, I'm studying a master degree and my research is about image processing.
