A buyer does not open a listing and ask what the mask IoU was. They look at the mirror stalk, the antenna, the gaps between wheel spokes, the glass, and the tire line where black rubber meets whatever floor you claim the car is sitting on. If asphalt from the old lot still glows through the spokes, or the car floats a finger-width above a showroom floor that never saw those tires, they feel it before they can name it. The click goes cold. The unit sits.
That is the sales problem in one frame. CarSegNet v2 is the still-image system I built so a dealership can take one usable lot photo and walk away with showroom-grade listing media: a composite, a cutout, and an alpha matte written as first-class artifacts. The buyer stakes are real. So are the ops stakes that never show up in a segmentation paper.
The ops case: same-day media without inventing ROI
A car that arrives on a Tuesday and waits until Thursday for a photo package is inventory that cannot earn an inquiry online. It is on the lot. It is paid for. It is not sellable as a listing until someone produces media. Same-day listing media turns delivery into something a shopper can find the same afternoon. That is money saved by shortening unsellable days, and money earned by putting the unit in front of demand sooner. I am not going to invent a dollar figure or an ROI percentage for that. CarSegNet and AutoLens measure matting, topology, and pipeline plumbing. They do not publish a controlled study of dollars per unit. The category of loss is still obvious to anyone who has watched a delivered car sit dark on the website while the lot fills with snow.
