The present invention is a lighting device attached to the front of a camera device, such as a smartphone, and connected to the camera device to produce an appropriate lighting environment for the acquisition of good quality animal nose pattern images by taking into consideration such factors and ambient lighting as well as the color of the nose.

Lighting device for acquiring nose pattern image

A method for implementing animal nose pattern biometric identification system on a mobile device using visual guides displayed on a screen to position a camera in relation to a nose. Suitable types and sizes of visual guides are selected for each animal nose and are superimposed on the perimeter of the nose or features of the nose that are displayed on the screen through the camera. The visual guides help define areas for autofocusing and real-time or post-acquisition image quality assessment, as well as the region of interest used for biometric matching.

Device for recognizing animal's identity by using animal nose prints

The present invention relates to an animal recognition apparatus including an image recognition unit to generate, enroll, verify, and identify the raw or processed nose pattern code from the acquired nose pattern image, and to an animal recognition method including a nose pattern image acquisition step and nose code generation, enrollment, and matching steps.

Device and method for recognizing animal's identity by using animal nose prints

The present invention relates to an apparatus and method of an animal recognition using nose patterns, and particularly to an apparatus and method of an animal recognition comprising a body stabilizer unit to minimize movement of the subject animal for optimal nose pattern image acquisition, an image acquisition unit to obtain and store the nose pattern image, and an image recognition unit to generate, enroll, verify, and identify the raw or processed nose pattern code from the acquired nose pattern image.

The present invention relates to a method and apparatus for identifying a living eye, in which IR LED lighting and lighting for varying the ambient illumination are installed on the front surface or one side of an iris recognition camera so as to determine whether an iris of an eye is an iris of a living eye when capturing an iris image by the iris recognition camera, using one or more criteria of whether the ratio of the sizes of the iris and pupil changes by the variation of the ambient illumination, whether the number or location of the IR LEDs focused on the iris and/or the pupil changes, whether the region of the iris image changes by eye blinking, and whether the direction of the gaze changes.

This invention relates to an outline font, and more particularly to a progressive renderable outline font and methods for transforming and rendering the same. Its purpose lies in supplying a progressively renderable Font which can be varied according to the quantity of the data composing the font. The Progressively Renderable Font has the function of controlling the display speed and the quality of the font. For example, if the hardware speed is relatively slow and a high quality font is not needed, only a part of the font data will be transmitted and displayed. On the contrary, if the hardware speed is relatively fast and high quality font is needed, gradually increased data will be transmitted and displayed. Therefore, a font can be transmitted and displayed using minimal data without sacrificing quality. On the other hand, in case of the environment, all the data can be transmitted and displayed so that the quality of the font can be fully realized.

The present invention relates to an outline font. The purpose lies in supplying a transforming and rendering method in the shape where the important form of the shape, such as the thickness of the stroke, will be maintained from the basic shape, and at the same time the whole size of the shape can be fitted into a given bounding box. The present invention supplies the transformation method of a handwriting font including searching for the medial axis of a given element, obtaining contact points by using maximal inscribed circles with the medial axis and points of the medial axis as a center, and applying the information about the medial axis points and the contact points in case of a transformation of the element in the transformation method of handwriting where a given element can be optionally transformed in sizes in order to achieve the purpose. The present invention enables the transformation of the shape. In resizing the given element from the box surrounding element to the box where the new element is placed, the important form of the shape, such as the thickness of the stroke, is maintained, and at the same time the size of the whole is transformed in accordance with the optionally given box.
