Disclosed herein is a method of determining a user profile based on a set of user-selected images, a method of selecting images from an image database of digital images based on a user profile, a computer system and a computer program product. The method of determining a user profile comprises obtaining a set of reference images, wherein each of the reference images is associated with a category from a plurality of categories; determining a sample feature vector for a sample image and a reference feature vector for each of the reference images, wherein the feature vector of an image is associated to features of the image; determining a similarity metric between the sample image and each of the reference images based on the sample feature vector and the reference feature vectors; selecting nearest reference images for each category, wherein the similarity metric between the sample image and a nearest reference image meets a minimum assignment similarity criterion and a maximum assignment similarity criterion; and determining the user profile by calculating an assignment probability for each category based on the similarity metrics between the sample image and the nearest reference images of the respective category.

Image selection from a database

A method of and apparatus for producing a validated print-out. The method includes creating a modified virtual image which includes the data from the original virtual image and a virtual original series of color patches representative of a color gamut. A printed series of the color patches representative of the color gamut using a spectrophotometer to provide a spectrophotometer output is scanned. The spectrophotometer output is analyzed using the processor to compare the output to an admissible range stored in a memory. If the output is within the admissible range, the print-out of the modified virtual image is validated. If the output is outside of the admissible range, the print-out of the modified virtual image is either validated after an analysis of the position of the data points of the modified virtual image in relation to an admissible color gamut, or the modified virtual image is changed.

Proofing method and apparatus that selects the kind of media type and transformation of the input color gamut based on the output device and the results of comparison with a scanned image using a spectrophotometer
