Abstract

A purpose of the present invention is to easily select an appropriate processing format, an appropriate parameter, or the like by predicting a process result that varies according to content of data before executing the process.

According to the present invention, provided is an information processing device including: a feature amount extraction unit configured to extract a feature amount of data serving as a target of a process; a feature amount matching unit configured to match the feature amount with one or more reference feature amounts associated with a prediction result of the process in a database; and a result prediction unit configured to predict a result obtained in a case where the process is executed for the data, on the basis of a result of the matching.

Claims

1. An information processing device comprising:

a feature amount extraction unit configured to extract a feature amount of data serving as a target of a process;

a feature amount matching unit configured to match the feature amount with one or more reference feature amounts associated with a prediction result of the process in a database; and

a result prediction unit configured to predict a result obtained in a case where the process is executed for the data, on the basis of a result of the matching.

2. The information processing device according to claim 1, further comprising:

an execution control unit configured to control execution of the process on the basis of the prediction result.

3. The information processing device according to claim 2,

wherein the execution processing unit decides a setting of the process on the basis of the prediction result.

4. The information processing device according to claim 3,

wherein the setting includes a format of the process or a parameter of the process.

5. The information processing device according to claim 2,

wherein the execution control unit decides whether or not to execute the process on the basis of the prediction result.

6. The information processing device according to claim 2, further comprising:

a result evaluation unit configured to evaluate a result of the execution; and

a database updating unit configured to update the database on the basis of the feature amount and a result of the evaluation.

7. The information processing device according to claim 6,

wherein the database updating unit adds data indicating that the feature amount is treated as a reference feature amount to the database in a case where the matching has been failed.

8. The information processing device according to claim 1,

wherein the result prediction unit predicts a compression rate for compressing the data, quality of the data after compression, and identity between the data before compression and the data after compression.

9. The information processing device according to claim 1,

wherein the result prediction unit predicts cipher strength for encrypting the data.

10. The information processing device according to claim 1,

wherein the result prediction unit predicts process time or an amount of resource consumption for executing the process on the data.

11. The information processing device according to claim 1, wherein

the data includes data for displaying an image, and

the feature amount extraction unit extracts a feature amount that is independent of resolution and rotation of the image.

12. An information processing method comprising:

extracting a feature amount of data serving as a target of a process;

matching, by a processor, the feature amount with one or more reference feature amounts associated with a prediction result of the process in a database; and

predicting a result obtained in a case where the process is executed for the data, on the basis of a result of the matching.
