Sentence examples for hand contour from inspiring English sources

Fifthly, we retrieve the hand contour, with a linear 'Roberts' filter.

(f) I c, obtained from Roberts linear filtering, containing the expected hand contour.

In Section 3 we explain how optical flow is adapted as a hand contour detection method and how adequate preprocessing methods yield a binary image containing only the hand contour.

Since a sparse version of the optical flow was chosen, these points are mainly focused on the hand contour.

The preprocessing operations presented in this subsection allows us to focus on an ROI and isolate the hand contour.

The visual results show that despite a complex background, a hand contour is correctly retrieved for various hand colors.

This is due to the low number of coefficients required to afford a moderate computational load: contours are smoothed and some details of the hand contours are skipped.

We wish to overcome this limitation and characterize non-star-shaped contours, because the hand contours considered in this paper are mostly non-star-shaped.

In the general case, hand contours are not star-shaped since it is (nearly) impossible to find a pole for which the relation ρ=f holds for all contour pixels.

Referring to an analogous scheme in [4], one can appreciate some improvements that were recently carried out to further enhance the detection of hand contours, essentially the optical flow combined with elliptic fitting, a dedicated preprocessing to help in the selection of the largest set of connected pixels, and a new method to ensure the invariance to rotation.

The implant site at times needs to be contoured with burr whereas simple hand contouring is sufficient.
