摘要:
An apparatus and method for recognizing a specific area of an image in a portable terminal. More particularly, an apparatus and method are for determining feature points with very high similarities as one group when the portable terminal recognizes a building included in an image or a picture, and for estimating a matching relation of the group to improve building recognition performance. The apparatus includes an image analyzer configured to, upon extracting feature points used for building recognition, classify feature points with similarities among the extracted feature points into a group, and recognize a building after estimating a matching relation by regarding the classified group as a feature point.

摘要:
Disclosed is a method for photographing a panoramic image including the steps of recognizing movement of a corresponding photographing apparatus by comparing a current real-time input image with a previous image through a motion estimation mechanism with exposure compensation, determining a time to photograph each next picture by determining whether movement in a photography direction reaches a preset threshold value, and photographing each next picture by manual or automatic operation at the determined time.
摘要:
The present invention relates to a portable book holder that can be converted from its original size into a small size if a user wants to carry the portable book holder, thereby making it easy to be carried, adjust a supporting area in accordance with the sizes of a book, and allow a user to adjust a book holding stand to his or her desired arbitrary angle.
摘要:
A polyester resin composition comprises (A) about 100 parts by weight of polyester resin with a melting point greater than about 200° C. and including repeat units of Formula 1; (B) about 0.1 to about 80 parts by weight of white pigment; and (C) about 0.01 to about 80 parts by weight of filler. The polyester resin composition of the present invention does not exhibit deteriorated reflectance and impact strength and also has good heat resistance, non-yellowing property and humidity resistance and can be used in a light emitting diode (LED) reflector.
