Fourier Transform - OpenCV 3.4 with python 3 Tutorial 35

[@朱先生-g4n]

thanks for teaching!It's quite useful for my study!

[@serhatylmaz1199]

how can we use fourier transform for object detection on tensorflow

[@sirphira3898]

Thanks!
This tutorial helped me alot while doing my d.i.p assignment

[@pysource-com]

Awesome :)

Hey there, Thxx for the video. You help me so much, but i didn't understando why you multiply the log for 20? I made a test and if has no number there the image will be black, but why 20? why not other value?

[@lukasschneider6329]

i suspect it was just change of scale so that limits in the plot needn't be changed. using imshow gives you the same fourier characteristics.

[@thewokal5641]

because he cahnged it to decibel, so that high frequencies arent too far away from the center

Thanks sir, this video was help me a lot

Thank's for You, how i can concatenate 4 images (two rows and two columns)

[@gilneyjunior8285]

First, you concatenate the images in rows horizontally (using axis=1). After, you concatenate the rows vertically (using axis=0)

Thanks for you video which was very clear to me.

an how can i convert the séctrum into an image again?

[@anantj18]

When the magnitude spectrum is plotted without converting it to a uint8 type array, the plot looks different. Especially the black region in the centre is not there. Why does this happen?

[@mankaransingh2599]

uint8 only represents 256 values. we need continous values

[@Hi-eul]

@@mankaransingh2599 continuous or discrete?

[@ignaciolanzani6542]

love it , thanks!

[@anujpatel6438]

Can you please make tutorials on open-3d

[@Raj-sz9pg]

Thank you

[@pradeepgaur9047]

honestly, those spectrums looked more different to me, than the alphabets themselves :D

[@DiamondSane]

nice video
