Abstract

An approach is provided for acquiring media corresponding to a target expression. The expression platform receives a request specifying one or more target expressions. Next, the expression platform causes, at least in part, acquisition of media including an expression of one or more emotions. Next, the expression platform performs recognition analysis on the media to extract expression data. Next, the expression platform matches the extracted expression data against reference data corresponding to the one or more target expressions. Then, the expression platform computes a similarity score between the extracted expression data and the matched target expression.

Claims

1. A method comprising:

receiving a request specifying one or more target expressions;

causing, at least in part, acquisition of media including an expression of one or more emotions;

performing recognition analysis on the media to extract expression data;

matching the extracted expression data against reference data corresponding to the one or more target expressions; and

computing a similarity score between the extracted expression data and the matched target expression.

2. A method of claim 1, wherein the request specifies context information for acquiring the media, further comprising:

determining extent of the context information included in the media;

computing the similarity score based further on the determination.

3. A method of claim 1, further comprising:

receiving a request for specifying a time limit for acquiring the media; and

determining whether the media was acquired within the time limit.

4. A method of claim 1, further comprising:

causing, at least in part, capturing of additional media immediately before or after the acquisition of the media;

performing recognition analysis on the additional media to extract additional expression data; and

matching the additional expression data against the reference data of the matched target expression to verify the matching of the extracted expression data.

5. A method of claim 1, wherein the one or more emotions include fear, anger, surprise, contempt, disgust, happiness, and sadness, and wherein the expression includes a facial expression, a body expression, or a combination thereof.

6. A method of claim 1:

receiving an input for selecting the one or more target expressions,

wherein the matching of the extracted expression data is against the selected one or more target expressions.

7. A method of claim 1, further comprising:

causing, at least in part, sharing of the acquired media, the extracted expression data, the one or more target expressions, the matched target expression, or a combination thereof.

8. A method of claim 1, wherein the reference data is collected by crowdsourcing.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive a request specifying one or more target expressions;

acquire media including an expression of one or more emotions;

perform recognition analysis on the media to extract expression data;

match the extracted expression data against reference data corresponding to the one or more target expressions; and

compute a similarity score between the extracted expression data and the matched target expression.

10. An apparatus of claim 9, wherein the request specifies context information for acquiring the media, and wherein the apparatus is further caused, at least in part, to:

determine extent of the context information included in the media;

compute the similarity score based further on the determination.

11. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

receive a request for specifying a time limit for acquiring the media; and

determine whether the media was acquired within the time limit.

12. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

capture additional media immediately before or after the acquisition of the media;

perform recognition analysis on the additional media to extract additional expression data; and

match the additional expression data against the reference data of the matched target expression to verify the matching of the extracted expression data.

13. An apparatus of claim 9, wherein the one or more emotions include fear, anger, surprise, contempt, disgust, happiness, and sadness, and wherein the expression includes a facial expression, a body expression, or a combination thereof.

14. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

receive an input for selecting the one or more target expressions,

wherein the matching of the extracted expression data is against the selected one or more target expressions.

15. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

share the acquired media, the extracted expression data, the one or more target expression, the matched target expression, or a combination thereof.

16. An apparatus of claim 9, wherein the reference data is collected by crowdsourcing.

17. An apparatus of claim 9, wherein the apparatus is a mobile phone further comprising:

user interface circuitry and user interface software configured to facilitate user control of at least some functions of the mobile phone through use of a display and configured to respond to user input; and

a display and display circuitry configured to display at least a portion of a user interface of the mobile phone, the display and display circuitry configured to facilitate user control of at least some functions of the mobile phone.

18. A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

receiving a request specifying one or more target expressions;

causing, at least in part, acquisition of media including an expression of one or more emotions;

performing recognition analysis on the media to extract expression data;

matching the extracted expression data against reference data corresponding to the one or more target expressions; and

computing a similarity score between the extracted expression data and the matched target expression.

19. A computer-readable storage medium of claim 18, wherein the request specifies context information for acquiring the media, and wherein the apparatus is caused, at least in part, to further perform:

determining extent of the context information included in the media;

computing the similarity score based further on the determination.

20. A computer-readable storage medium of claim 18, wherein the apparatus is caused, at least in part, to further perform:

causing, at least in part, capturing of additional media immediately before or after the acquisition of the media;

performing recognition analysis on the additional media to extract additional expression data; and

matching the additional expression data against the reference data of the matched target expression to verify the matching of the extracted expression data.
