Abstract

A method of altering a distinctive image within a digital video file is provided, wherein data representing a set of images in the file is selected. The data is then scanned for a pixel having a color associated with the distinctive image. Then additional pixels having the color are located in a plurality of directions relative to the first pixel. A shape is determined based on the location of pixels, and the shape compared to the distinctive image so that a probability can be determined as to whether the shape represents the distinctive image. If the probability exceeds a confidence level, then the distinctive image is altered.

Claims

1. A method of altering a distinctive image within a digital video file, comprising:

a) selecting data representing a set of images within the digital video file;

b) scanning said data for a first pixel having a color associated with the distinctive image;

c) searching for additional pixels having said color in a plurality of directions relative to said first pixel;

d) determining a shape associated with said additional pixels of said color;

e) determining if a plurality of pixels in a relative position to said shape has a color conforming to the distinctive image;

f) calculating a probability that said image is present in said data;

g) if said probability exceeds a confidence level, altering said distinctive image;

h) repeating steps a) through g) on following data representing subsequent images until said calculated probability does not exceed said confidence level; and

i) determining a context that specifies a location depicted in the images of the digital video file based at least in part on the distinctive image; and

j) altering the distinctive image with a second distinctive image throughout the digital video file.

2. The method of claim 1 wherein the distinctive image is a trade-mark.

3. The method of claim 2 wherein the method further comprises:

determining an image of a product associated with said trade-mark.

4. The method of claim 3 wherein said image of said product is altered.

5. The method of claim 4 wherein said image of said product is altered by substitution for a second image of a second product.

6. The method of claim 4 wherein said image of said product is altered by addition of data representing an image of a related product to said data representing a frame.

7. The method of claim 4 wherein said image is altered by removal of said image of said product from said data.

8. The method of claim 1 wherein said steps are carried out by one of:

a) a computer displaying the digital video file;

b) a server storing said digital video file;

or

c) a computer receiving said digital video file from a server and transmitting said digital video file to a second computer .

9. The method of claim 1 wherein said second image is substituted based on the geographical location of said computer requesting said digital video file.

10. The method of claim 1 wherein said alteration is based on a history of purchase behavior of a user.

11. The method of claim 1 wherein when determining the probability, considering the mathematical relationship of components of the distinctive image.

12. The method of claim 1, wherein the set of images are selected at predetermined time intervals from the digital video file.

13. The method of claim 1 wherein the context includes blocking information, and the alteration of the distinctive image does not alter the blocking information.

14. A system for altering an image of a product within a digital video file, comprising:

a) a first computer requesting the digital video file from a second computer over a network;

b) at least one of said first or second computers configured to;

i) select data representing a set of images within the digital video file;

ii) scan said data for a first pixel having a color associated with an image;

iii) search for additional pixels having said color in a plurality of directions relative to said first pixel;

iv) determine a shape associated with said additional pixels of said color;

v) determine if a plurality of pixels in a relative position to said shape have a color conforming to said image of a product;

vi) calculate a probability that said image is present in said data; and

vii) if said probability exceeds a confidence level, alter said image of a product;

viii) repeat steps i) through vii) on data representing images selected from the group consisting of previous data representing images and subsequent data representing images, until said calculated probability does not exceed said confidence level; and

ix) altering the image with a second image throughout the digital video file; and

x) determining a context that specifics a location depicted in the digital video file based at least in part on the distinctive image.
