Comments: This image set shows a background environment consisting of a set of ÒofficeÓ objects– for example lamps, a table, and boxes. The purpose of the image set is to provide a set of clutter scenes to composite with the bluescreened images in the chair, redchair, and cart image sets.  The lower left portion of the images is mainly empty so that the bluescreened images can be added in to make realistic-looking views with minimal adjustment.  The set of views spans roughly 60 degrees of rotation in the plane parallel to the floor, and variation in scale and camera elevation is about the same as for the cart and chair images. Specifically, the objects are about 2-3 m away from the camera, the height of the camera is between 1.5 m and 2m, and the total variation in object scale across all views is about 20%. To induce appearance variation in the background between views, we modified the poses of each background object and shuffled their relative positions every 5 to 8 images. The camera translates from side to side between views and rotates slightly. 

Vista Parameters: (sigma, lowThreshold, highThreshold,minimumEdgeLength, accuracy, granularity, magnitude) = (3,10,35,50,2.0,4.0,20.0)
