Abstract: This paper describes a simple and intuitive method for controlling the automatic layout of a photo-album. It empowers a consumer-user by taking advantage of their knowledge of the importance of particular people (the cast) in their story. Currently automatically detected faces are manually tagged. A cast of identified people is established which specifies the visual impact (emphasis) of a person desired in the presentation. This provides a powerful means of controlling the presentation without any direct manipulation. It enables a user to generate different person-biased variants from the same photo-collection and so tailor a presentation to a particular audience. The idea is to allow the user to control the overall intended emphasis given to each member of the cast. This target emphasis has to be achieved within the aesthetic constraints established by a user selected style. For each potential photo-selection, the style is responsible for enumerating the possible template layouts. This enumeration reduces the layout-problem to one of: selecting from a set of templates, and deciding which photo to put in a slot of the template. This allows the use of a search to identify the best combination of template and photo-selection. The search discriminates candidate layouts by comparing the emphasis measured in a particular layout against the desired target emphasis.
