    Thank you so much, Dr. Verma. That was very helpful. I will be forever grateful for this wavelets series videos. I have searched many websites and wasted many an hour because I was not getting the thorough knowledge you provided in just a single video.

    Concise yet informative. The use of MATLAB examples and commands throughout the lecture greatly helped convey the concept. This video was perfectly executed.
    Thank you for your time and effort! Your explanation immensely helped me in my undergrad project!

    Hello Dr verma , how are you? I wanted to ask you something. What are the necessary steps to create an image processing project using FPGA and VHDL? Can you give me any advice? I want to use the Haar wavelet but I don't know where to start.

    • @exploringtechnologies9
      @exploringtechnologies9  6 месяцев назад

      1. First you decide the problem which you want to solve.
      2. Let your problem is denoising image with wavelet filters.
      3. Then write matlab code for that.
      4. Convert that code to vhdl using matlab coder.
      5. Load the program to FPGA.
      6. The challenge will be the camera interface with FPGA.

    The tabular figure must be modified in a way that all the boxes have the same area. I mean their height must be decrease from down to up, in this slide.

      Few slides are my own original content and other slides include material from various other resources such as books of S. Mallat, I. Daubecheis, M. Misity and matlab documentation.

    • @exploringtechnologies9
      @exploringtechnologies9  Год назад

      For any transform, the basis functions must be orthogonal. So wavelets as basis functions are orthogonal. Soon i will make a video on understanding concepts of orthogonality, biorthogonality, basis functions.

      @@exploringtechnologies9 thank you. I just want to get a better understanding of the equation of inverse continuous wavelet transform(icwt).
      According to the icwt equation, in my understanding if it’s correct , the icwt of one cwt coefficient should be in the form of wavelet. But the results is just a point, the values equal to zero other than the translation point of the selected coefficient.

  • @htchtc203

    Sir, is it fair to say the Mortlet wavelet is nothing more that a common sinusoidal basis multiplied by a certain window funktion? If that holds true, then Mortlet walelet is nothing more than STFT with very specific window function (instead of rectangular window function).

    • @exploringtechnologies9
      @exploringtechnologies9  2 года назад

      No.
      There is difference between STFT and Wavelet transform. Wavelet transform doesn't suffer with ambiguity of window size selection.
