Is there anyone who master the use of MFC in handling data noise and smooth, I want to use MFC to read data to calculate, but data fluctuation is too big, the need for noise reduction and smoothing,

CodePudding user response:

No problem, as long as you know the noise reduction, the algorithm principle of charged!
Can also search algorithms for noise reduction in net!

CodePudding user response:

I use the median filtering, and smoothing at 9 o 'clock, two-dimensional, effect is good, you can have a try, if it is a one dimensional data is simpler,

Search "low-pass filter"

CodePudding user response:

Literally get a moving average, three or five points of sliding

CodePudding user response:

This has nothing to do with MFC, MFC just library, written in c + + algorithm, have various libraries available, such as the world's best GSL, or TP++ signal processing

what great spirit in the discussion of all stripes upstairs!!!!!! Why I couldn't understand a word!!!!!!!!!!

The original poster said "data", the image data or audio or video???

CodePudding user response:

you are you sure this post really belong to a" base class "?
Why didn't I learn MFC learned this aspect of the "base"???????

Eldest brother, I is to make a noise reduction of sensor measured data and smoothing processing, processing of graphics can be used?

CodePudding user response:

See this code in image smoothing and noise reduction, ask what do you mean?
dValue=https://bbs.csdn.net/topics/0.0;

for(m=0; M<3; M++)
for(n=0; N<3; N++)
dValue=https://bbs.csdn.net/topics/dValue+H [m] [n] * Value [m] [n].

dValue=https://bbs.csdn.net/topics/dValue * K;

PBits [lTotal]=int (dValue + 0.5);

Whether the resources, in the final analysis is the data, and is the image or video have what relation, general algorithm
