Pray god give some ideas to describe curve comparison similarity from the Angle of the shape description, but I don't know how to describe the trend

CodePudding user response:

Compare the curve of maximum, minimum, the sequence of inflection point? Or some domain transformation curve do?

CodePudding user response:

Have thought of these, but there is no single one how on behalf of this curve, I thought about the shape description to describe curve, but how to extract features from description

CodePudding user response:

Still more intuitive graphical expression, curve of different colors, and the curve after scaling and phase adjustment, making them easy to compare,

CodePudding user response:

Affirmation is to use some data to reflect the change, intuitive view of this research is meaningless, and the main one extreme value point is not enough to reflect the features of a curve, how to put these characteristics (such as many extreme value point) fusion together response curve of the trend

CodePudding user response:

Could you tell me the original poster with what method to solve problems, encountered the same problem?
