4208 results about "Canis lupus familiaris" patented technology

The domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.

Registering control point extracting method combining multi-scale SIFT and area invariant moment features

InactiveCN101714254AMake up for defects that are susceptible to factors such as noiseImage analysisFeature vectorImaging processing
The invention discloses a registering control point extracting method combining multi-scale SIFT and area invariant moment features, relating to the field of image processing. The invention solves the technical problems of how to extract stable and reliable feature points in the image registering process. The method comprises the following steps of: firstly, carrying out continuous filtering on images by utilizing Gauss kernel functions to generate the DOG scale-space by combining with a downsampling method, and seeking and calculating space and scale coordinates of a local extremum. Then, forming the feature vectors of a key point by utilizing directional gradient information, and obtaining an originally matching key point pair through the Euclidean distance; and then calculating local area HU invariant moment features by taking the originally selected key point as the center, and screening out a finally accurate and effective registering control point by combining with the Euclidean distance. The method combines the multi-scale features of an SIFT arithmetic and the image local area grayscale invariant moment features, thereby effectively improving the stability and the reliability of extracting multisensor image registering control point pairs.

Appliance for dissuasion of a dog from barking

In a device adapted to dissuade a dog from barking, there is provided a reservoir of spray material associated with a collar which encircles the dog's neck. The reservoir includes at least one wall member defining an interior volume for the receipt of spray material therein. The reservoir includes a first dimension (i.e., a centerline) which lies within the median sagittal plane of an erect dog which is facing forward, thereby orienting one portion of the interior of the reservoir vertically lowermost. An exit port is provided for the transport of spray material from the interior to the exterior of the reservoir. A semi-rigid, lengthwise substantially non-compressible, conduit having a first end thereof connected in fluid flow communication with the exit port, extends from the exit port and terminates at its opposite and open end at the vertically lowermost interior portion of the reservoir when the present appliance is mounted at a location on the collar beneath the lower jaw of the dog. The length of the conduit is chosen to exceed the straight-line distance between the exit port and the vertically lowermost portion of the reservoir by an amount sufficient to provide for wedging of the conduit against at least one interior wall of the reservoir opposite the exit port and preferably opposite to terminal open end of the conduit.
