In early 2016, the authors created a small installation for the window of the Constant office in the Saint-Gilles neighborhood of Brussels. For forty days, a camera was set up to record short sequences of video frames, triggered by the presence of a "face" as detectable by a standard "face-detection" algorithm[^cascade]. When a face was detected, a short sequence of frames would be recorded, and the regions of the image detected as "faces" would be replaced by faces similarly detected in an archive of images, including images from the SICV. Many of the detected "faces", both from the street and the archive, would be considered "false positives" -- images not of faces but of car hubcaps, the folds of a puffy jacket, the typography of a book page, or the play of light on the opposite building. A number of monitors were arranged facing the street in a reversal of the traditional surveillance setup, making the recording apparatus and processing pipeline as visible as possible, showing the transformation step by step to its subject. Once the recordings were completed, a short animation loop was produced and displayed on a central monitor. One Saturday evening, the image above was recorded.
