Method and apparatus for production of helical springs by spring winding

A method and an apparatus for production of helical springs by spring winding. The method of producing helical springs by spring winding with a numerically controlled spring winding machine includes feeding a wire, controlled by an NC control program, through a feed device to a forming device of the spring winding machine, forming a helical spring from the wire with tools of the forming device, defining a desired nominal geometry of the helical spring and an NC control program adapted to produce the nominal geometry, measuring an actual position of a selected structural element of the helical spring relative to a reference element at least one measurement time, which occurs after a start and before an end of production of the helical spring in a measurement area which is at a finite distance from the forming device in a longitudinal direction of the helical spring, wherein the distance is less than an overall length of the finished helical spring, comparing the actual position with a nominal position of the structural element for the measurement time to determine a current position difference, which represents a difference between an actual position and the nominal position at the measurement time, and controlling the position by at least one of the tools of the forming device, which tool determines a pitch of the helical spring as a function of the position difference.

Saliency detecting method applied to static image human segmentation

The invention discloses a saliency detecting method applied to static image human segmentation. The method comprises the following steps of performing superpixel segmentation on a static image to be detected; performing face detection on the image after the superpixel segmentation to acquire a face area; performing skin color detection on the face area to acquire skin color information; performing color uniqueness calculation and color spatial distribution calculation according to the skin color information to acquire a color uniqueness value with the skin color information fused therein and a color spatial distribution value with the skin color information fused therein; performing saliency calculation according to the acquired color uniqueness value and the color spatial distribution value to acquire a saliency map used for static image human segmentation. Based on a conventional saliency detecting method, the method provided in the invention makes the skin color well detected by making the skin color information fused in the color uniqueness calculation and color spatial distribution calculation. The human skin color saliency is enhanced. Better and more accurate static image human segmentation effects are achieved. The method can be widely applied to the image processing field.

Improvement method of grating anti-counterfeiting phase modulation based on color values

The invention discloses an improvement method of grating anti-counterfeiting phase modulation based on color values. The method comprises the following steps: step 1: selecting and decomposing a hostimage; step 2: determining a hidden area of the host image and anti-counterfeiting information: at least one color channel of the host image has a hidden area where the anti-counterfeiting informationcan be set, the hidden area has s*s pixel points, the color channel where the hidden area is located is recorded as a mother set, the color values of all pixel points of the hidden area on the motherset are the same and are recorded as alpha, and the rest color channels are 3 secondary versions; step 3, performing halftone processing on the host image; and step 4: hiding the anti-counterfeitinginformation: selecting the anti-counterfeiting information that needs to be hidden, establishing a lattice point selection area in the hidden area corresponding to the contour of the anti-counterfeiting information in image processing software, recording lattice points in the lattice point selection area as a set A, and performing phase modulation on the lattice points in the set A. By adoption ofthe improvement method disclosed by the invention, the modulable angle range of the lattice points is expanded.
