The washing machine classification accuracy is 96.85% (top-left); the stand-mounted air-conditioner accuracy is 96.85% (top-right). The centerlines are arranged in the order of wall-mounted air-conditioners (93.75%), robotic vacuum cleaners (99.9%). The lines at the bottom are arranged in order of vacuum cleaners (96.1%) and microwaves (85.9%), for all of which we extract only the object area and use the image for classification
