    De moderne consument vindt het steeds belangrijker om bewuste keuzes te maken. Met 'Ecobranding' en 'Green marketing' kunnen producenten hier handig op inspelen. Door te investeren in milieuvriendelijke teeltmethoden kunnen zij hun producten laten onderscheiden op gebied van duurzaamheid. Maar duurzaamheid is een breed begrip. Er kan bijvoorbeeld gekeken worden naar waterverbruik, ecotoxiciteit, diervriendelijkheid of levensduur. Een steeds vaker gebruikt criterium voor duurzaamheid is de Carbon Footprint

    Automating the construction of scene classifiers for content-based video retrieval

    This paper introduces a real time automatic scene classifier within content-based video retrieval. In our envisioned approach end users like documentalists, not image processing experts, build classifiers interactively, by simply indicating positive examples of a scene. Classification consists of a two stage procedure. First, small image fragments called patches are classified. Second, frequency vectors of these patch classifications are fed into a second classifier for global scene classification (e.g., city, portraits, or countryside). The first stage classifiers can be seen as a set of highly specialized, learned feature detectors, as an alternative to letting an image processing expert determine features a priori. We present results for experiments on a variety of patch and image classes. The scene classifier has been used successfully within television archives and for Internet porn filtering
