Abstract: Disclosed is a method and apparatus for detecting and ranging cloud features. The method comprises: obtaining image data(e.g. using a camera (200); classifying, as a cloud feature, an image segment (502-508) of the image data; determining a plurality of moments of the image segment (502-508); using the determined plurality of moments, determining a geometric representation of that image segment (502-508); and, using the geometric representation, determining a distance between the cloud feature represented by that image segment (502-508) and an entity that obtained the image data.

Abstract: Disclosed is a method and apparatus for detecting cloud features. The method comprises: obtaining image data (e.g. using a camera), the image data defining a plurality of pixels and, for each pixel, a respective luminance value; defining one or more intervals for the luminance values of the pixels; partitioning the image data into one or more image segments (502-508), each respective image segment (502-508) containing pixels having a luminance value in a respective interval; and classifying, as a cloud feature, each image segment (502-508) containing pixels having luminance value greater than or equal to a threshold luminance value (LT).

Abstract: Disclosed are apparatus and a method for detecting cloud features. The method comprises: obtaining (402) image data (401); identifying (404) regions of the image data corresponding to a below-horizon region and an above-horizon region; classifying (404) one or more parts of the above-horizon region as a cloud feature; determining (409) an identification model specifying a visual appearance of some or all of the parts of the above-horizon region that have been classified as a cloud feature; and using the determined identification model, classifying (404), as cloud features, those regions of the of the below-horizon region whose visual appearance is as specified by the identification model.

Abstract: A method of detecting at least one moving vehicle includes receiving (202) image data representing a sequence of image frames over time. The method further includes analysing (204-206) the image data to identify potential moving vehicles, and comparing (208-212) at least one said potential moving vehicle with a vehicle movement model that defines a trajectory of a potential moving vehicle to determine whether the at least one potential moving vehicle conforms with the model.
