The first stage uses a distance-transform guided watershed algorithm — no ground-truth labels needed — to isolate cells from a full blood smear image, recovering 75.95% of true cells across a 120-image NIH test set. The second stage runs EfficientNet-B0 to classify those cells by infection stage, hitting 98.36% overall accuracy. Crucially, it handles rare parasite stages: 87.5% accuracy on schizonts and 75.0% on gametocytes, versus 24.57% and 25.95% average precision for a Faster R-CNN baseline on the same classes. Per-cell Grad-CAM++ heatmaps let a microscopist see exactly which pixels drove each classification decision.\n\nThe stakes are real. In low-resource settings, the shortage of trained microscopists is the primary bottleneck to timely malaria diagnosis. AI tools that can flag infections — and show their work — could extend diagnostic capacity without requiring clinicians to trust a black box. The decoupled design also sidesteps a common trap: end-to-end detectors penalize models for cells that annotators missed, inflating error rates that reflect labeling gaps more than true model failure.\n\nThe benchmark here is an NIH dataset, not a prospective clinical trial, so translating these numbers to field conditions is the next unresolved question.","[\"ai\",\"health\",\"computer-vision\",\"research\"]","2026-07-02T04:00:00.000Z","2026-07-02T05:42:36.411Z","2026-07-02T05:42:39.092Z","published",null,[],"ai",[24,26,27,28],"health","computer-vision","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.00385",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
