DETERMINING DEPTH MAPS FROM IMAGES

DETERMINING DEPTH MAPS FROM IMAGES

A method generates a depth map from an image. In the method, a first depth data is generated that represents a first measure proportional to depth for pixels in the image using a first selected colour channel of the image, where the first depth data is calculated based on a minimum in intensity of t...

Zusammenfassung:A method generates a depth map from an image. In the method, a first depth data is generated that represents a first measure proportional to depth for pixels in the image using a first selected colour channel of the image, where the first depth data is calculated based on a minimum in intensity of the first selected colour channel of the image. A second depth data is generated that represents a second measure proportional to depth for pixels in the image, where the second depth data is calculated based on a maximum attenuation of a second selected colour channel of the image. The second depth data is filtered using the first depth data as a filtering guide to generate the depth map.
