Abstract
Abstract Disclosed is an inventive method for providing visual chat. A character image is read into memory representing a character a user wishes to be for the duration of the visual chat. Continuous frames of video images are then received, typically using video camera, which include image data of a person. The head image of the person is then tracked by the system, and portions of the head image are extracted from the video images. These extracted portions are preferably features of the person in the video image. Finally, the extracted portions of the head image are blended into corresponding areas of the character image, such that the features of the blended character image match the features of the person, and change as the features of the person change.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 words
A method for providing a visual chat session, the method comprising the operations of: reading a character image into memory; receiving video images including image data of a person, wherein the video images include a plurality of video frames; tracking a portion of a person image in the video images; executing an image gathering operation for obtaining a portion of the person image; and executing an influencing operation for influencing the character image utilizing the obtained portion of the person image; wherein the portion of the person image is obtained from a head portion of the person image, and wherein the influencing operation includes a blending operation comprising the operation of: blending the obtained portion of the person image into the character image to create a blended character image, wherein the blended character image includes features corresponding to features of the person image; the features of the blended character image change as the features of the person change; and at least one feature of the blended character comprises the obtained portion of the person image.
Claim 2
Independent Claim
175 words
A method for providing a visual chat session, the method comprising the operations of: reading a character image into memory; receiving video images including image data of a person, wherein the video images include a plurality of video frames; tracking a portion of a person image in the video images; executing an image gathering operation for obtaining a portion of the person image; and executing an influencing operation for influencing the character image utilizing the obtained portion of the person image; wherein the portion of the person image is obtained from a head portion of the person image, and wherein the influencing operation includes a blending operation comprising the operation of: blending the obtained portion of the person image into the character image to create a blended character image, wherein the blended character image includes features corresponding to features of the person image; the features of the blended character image change as the features of the person change; and at least one feature of the blended character comprises the obtained portion of the person image.
Claim 3
Dependent Claim
62 words
A method as recited in claim 1 , wherein the process of tracking the portion of the person image includes the operations of: determining a basic location of the head portion of the person image; processing the head portion of the person image; determining a line of symmetry for the head portion; and determining the location of features within the head portion.
Claim 4
Dependent Claim
34 words
A method as recited in claim 1 , further comprising the operations of: receiving audio signals; and processing the audio signals, whereby the audio signals may be processed to correspond to the character image.
Claim 5
Dependent Claim
