A method for authenticating the identity of a handset user is provided. The method includes: obtaining, a login account and a password from the user; judging whether the login account and the password are correct; if the login account or the password is incorrect, refusing the user to access an operating system of the handset; if the login account and the password are correct, sending the login account and the password to a cloud server, wherein the login account and the password correspond to a face sample image library of the user stored on the cloud server; acquiring an input face image of the user; sending the input face image to the cloud server; authenticating, by the cloud server, the identity of the user according to the login account, the password and the input face image.
Detection of an object in an image
The invention provides a method, system, and program product for detecting an object in a digital image. In one embodiment, the invention includes: deriving an initial object indication mask based on pixel-wise differences between a first digital image and a second digital image, at least one of which includes the object; performing an edge finding operation on both the first and second digital images, wherein the edge finding operation includes marking added edges; generating a plurality of straight linear runs of pixels across an image containing the object, wherein each of the plurality of straight linear runs starts and ends on an added edge and is contained within the initial object indication mask; and forming a final object indication mask by retaining only pixels that are part of at least one of the plurality of straight linear runs.
An electronic camera includes an imager. An imager outputs an electronic image corresponding to an optical image captured on an imaging surface. A first generator generates a first notification forward of the imaging surface. A searcher searches for one or at least two face images each having a size exceeding a reference from the electronic image outputted from the imager. A controller controls a generation manner of the first generator with reference to an attribute of each of one or at least two face images detected by the detector.
Object recognition apparatus and object recognition method
An object recognition apparatus recognizes an object from video data for a predetermined time period generated by a camera, analyzes the recognition result, and determines a minimum size and moving speed of faces of the video image recognized from the received frame image. Then, the object recognition apparatus determines a lower limit value of a frame rate and resolution from the determined minimum size and moving speed of the faces.
Generating data representative of a fragmented document
Systems and methods to generate data representative of a fragmented document are provided. A particular method includes using motion of a moving film to move multiple pieces of a document that has been fragmented. The method also includes capturing images of the pieces as the pieces are moving, wherein each of the images includes at least one side of at least one of the pieces. The method further includes processing the images to generate a data file including at least a portion of the document, where the portion is determined based on image data associated with two or more of the pieces.
Rain detection apparatus and method
A rain detection apparatus includes a camera that views a surface and a processor that captures an image from the camera. The processor generates a signal indicative of rain on the surface from information contained in the captured image and optionally drives a surface cleaning apparatus in response thereto. The apparatus captures images focused at a plurality of distances. The processor includes an edge detector that detects edges visible in the captured image and a difference structure that calculates the difference between the number of edges visible between differing images. The edge detector disregards edges close to areas of light larger than the largest raindrop that is desired or expected to be detected. The apparatus optionally includes a backlight, and the difference in numbers of edges between frames with and without the backlight illuminated are used to distinguish between background features and rain on the surface.
