Lecture 02 - Filtering - 2014

[@pedroazevedo3387]

You say that is a error on the slide, but there isn't... Because you are placing the right pixel as the middle....

Python code for histogram , hard coding it can be only 2 lines of code using reval() but it is similar to the slides. m = np.array([10, 20, 255, 6, 8, 25, 25, 9, 8, 7]) m = m.reshape(2, 5) print(m.shape) histo = {} for i in range(m.shape[0]): for j in range(m.shape[1]): if histo.get(m[i, j]): histo[m[i, j]] += 1 else: histo[m[i, j]] = 1 print(histo)

I think the gradient vector direction formula has a typo. It can be witnessed at around 23:40.

where is subtitle?

Thank you professor for the lecture, very smoothly delivered.

[@artikpark2140]

Is the reason why 42:31 the image is shifted right because the mask is applied through correlation? And then later 47:06 using the same mask its shifted left because the mask is applied using convolution? Thanks. The reason I'm asking is because in the textbook its shown the same way as in the video at 47:06. I think he just took those images out of context.

For Gaussian Filter Mubarak uses a constant for the standard deviation. He sets it by ha. nd Do we have to compute standard deviation for image intensity in real worldproblems

[@jinmingtang1545]

The C code of the histogram is really concise!

Hi , have you any article (pdf , html page ...) about filtring images ?

[@Berkeozbeek]

Very helpful, thanks from Turkey!

how can I practice what I learnt from these lectures? Is there a link to assignmenets?
