Have bosses know how outline of ellipse fitting within the image below?-CodePudding

How to understand the outline of ellipse fitting? Is to find out the outline of the surrounded the biggest ellipse?

CodePudding user response:

It also in how to select the profile and internal profile processing

This need to image vector quantization, is to convert the image into vector graphics, in vector graphics can be selected within the contour,

opencv without the corresponding function

Outer contour known?

refer to 6th floor early play big play nuclear war reply:

outer contour known?

outer contour, just don't know how to internally contour processing

CodePudding user response:

What are you going to take, the outline of the minimum adjacency rectangle, or within the contour point set?

CodePudding user response:

refer to eight floor early play play nuclear response:

what do you want to take, the outline of the smallest adjacency rectangle, or within the contour point set?

do to figure within the outline of ellipse fitting

how the image contour detection

CodePudding user response:

Directly take surrounded by an inner contour of the rectangle, rectangle width, is the length of the elliptical axis,

directly take surrounded by an inner contour of the rectangle, rectangle aspect, is the length of the elliptical axis,

how do rectangle within the selected contour, which there are outer contour?

CodePudding user response:

First binarization, down to a definite inner region

CodePudding user response:

Using photoshop to do the effect of binarization, not perfect, but belongs to the level of available:

then edge detection and contour directly, contour, the outer contour is drawn directly
