bowie-yolov8-multihead-trash-detection

bowie-yolov8-multihead-trash-detection is a pre-trained multihead model developed in a collaboration with Google.org and Google employees as part of the Google Impact Challenge: Tech for social good support that Bower got H1 2024. Which had as goal to create impact in the area of sustainability and waste. The purpose of the model is to detect items that could be recycled and inform how a product should be recycled.

The code that was used for training and evaluating the model can be found in our repository Seegull.

Taxonomy and description

Object type

Object Type	Description
Aerosol	A gas-tight, pressure-resistant container with a valve and propellant. When the valve is opened, the propellant forces the product from the container in a fine or coarse spray pattern or stream. Example: spray cans for paint, furniture polish, etc., under pressure. Excludes atomizers, as they do not rely on a pressurized container to propel product.
Battery
Blister pack	A type of packaging in which the item is secured between a preformed (usually transparent plastic) dome or "bubble" and a paperboard surface or "carrier." Attachment may be by stapling, heat-sealing, gluing, or other means. Often thermoformed from polyvinyl chloride, although other thermoplastics can be used.
Book
Bottle	A container with a round neck of relatively smaller diameter than the body, capable of holding a closure for retention of contents. It may be round, oval, square, oblong, or a combination, and is generally made of glass or plastic. Bottles can be disposable, recyclable, returnable, or reusable.
Box/Card/Tray/Crate	A non-specific term for a rigid, three-dimensional container with closed or semi-closed faces. Boxes and crates are made from various materials and may be used for storage or display. Trays are shallow containers used for display. Includes open-ended non-rigid containers like sleeves.
Gable Top	Package for liquids shaped like a gable top (triangle top), usually made of cardboard.
Aseptic Flat Top Carton	A rectangular-shaped, stackable package designed for liquids like juice or milk, made of multilayer laminated materials (e.g., Tetra Pak).
Tube	A cylindrical container sealed on one end, closed with a cap or dispenser on the other (e.g., toothpaste tube).
E-cigarette
Bulb
Can/Tin/Cylinder	Metallic, generally cylindrical containers of unspecified size, used for various items. Cylinders have rigid, straight sides with circular ends of equal size.
Cosmetics containers	Containers for makeup products like eyelashes, eyeliner, lipsticks, etc.
Cup/Tub/Bowl/Bucket	Flat-bottomed containers with a base of any shape, usually used for foods like ice cream, margarine, yogurt, and sour cream. They may or may not have lids and are typically made of paper, plastic, or other materials.
Jar	Rigid container made of glass, stone, plastic, or other material, with a large opening for storing products such as jams and honey.
Electronic device
Wrapper/Foil/Net/Bag/Flexibles	Flexible containers and materials used to enclose all or part of an item. Includes wrappers, gas-tight packs, nets for holding items, and bags or other flexible containers that may be sealed.
Jug	Cylindrical container with a handle, lid, or spout, used for holding and pouring liquids.
Lid/Cap
Other medical containers/Pharmaceuticals	Example: Nasal spray containers
Paper product	Includes white paper, newspaper, magazines, and other paper-based items.
Other

Material type

Material Type	Description
Hard plastic	Rigid plastics that maintain their shape, such as bottles, containers, toys, and household items made from materials like PET or HDPE.
Soft plastic	Flexible plastics that can be easily bent or scrunched, including plastic bags, wrappers, and films made from materials like LDPE.
Other plastic	Plastics that don't fit into hard or soft categories, possibly including bioplastics, mixed polymers, or specialized plastic products.
Fiber - Paper	Thin sheets made from pressed fibers, used for writing, printing, and packaging, such as office paper and newspapers.
Fiber - Cardboard / Paper Packaging	Thicker paper materials used for packaging, like corrugated cardboard boxes, paperboard cartons, and other sturdy paper packaging.
Fiber - Other	Other fiber-based materials not classified as standard paper or cardboard, such as insulation or specialized industrial fibers.
Metal	Materials made from metals like aluminum, steel, copper, and other metal alloys, used in cans, appliances, and construction materials.
Glass - Coloured	Glass materials that are tinted or colored, such as green or brown bottles and decorative stained glass items.
Glass - Non-coloured	Clear or transparent glass materials like window panes, clear bottles, and jars without any coloration.
Composite	Materials made from two or more different substances that remain distinct, such as Tetra Pak cartons combining paperboard, plastic, and aluminum.
Hazardous waste	Waste materials that are dangerous or potentially harmful to human health or the environment, like chemicals, batteries, and pesticides.
Electronic waste	Discarded electronic devices and components, including computers, smartphones, televisions, and electronic accessories.
Organic waste	Biodegradable waste derived from living organisms, such as food scraps, yard waste, and agricultural waste.
Textiles	Fabrics and cloth materials made from natural or synthetic fibers, used in clothing, upholstery, and linens.
Wood	Material derived from trees, including lumber, plywood, and wooden products used in construction and furniture.
Rubber & Leather	Materials made from natural or synthetic rubber (like tires) and animal hides (leather goods such as shoes and belts).
Other	Materials that do not fit into any of the specified categories above, including unique or miscellaneous items.
