Silkworm Egg Development Intelligent Recognition by THz Imaging

2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz), 2021
Multidisciplinary cross-integrated researches and interdisciplinary cooperation can help inspire new ideas and accelerate development of disruptive application. Here we combine terahertz (THz) imaging technology and artificial intelligence (AI) algorithms to realize the dynamic monitoring of silkworm egg development.

Cracked egg recognition based on machine vision

Computers and Electronics in Agriculture, 2019
Abstract Since the cracks on eggshell are difficult to be recognized due to the surrounding highlighted dark spots on the egg surface under back-light illumination, a new method to identify the cracks based on machine vision was proposed. After analyzing the characteristics of the cracks in the image of the egg under the back-light illumination, a ...

Mechanisms of avian egg recognition: adaptive responses to eggs with broken shells

Animal Behaviour, 1988
Abstract Avian eggs may be broken when winds jar nests and by other disturbances. The presence of broken eggs can threaten the survival of remaining intact eggs, but possible behavioural responses to this selection pressure have received little attention, especially in passerines.

Egg recognition and chick discrimination in colonial breeding birds

Behavioural Processes, 2019
Theory predicts that parents will not raise unrelated offsprings. For colonial breeding birds, evolving an ability to recognize their own eggs and chicks can prevent misdirecting parental behaviour. To verify this hypothesis, egg recognition experiments were performed on colonial breeding Chinese pond herons (Ardeola bacchus) and cattle egrets ...

Conflict between egg recognition and egg rejection decisions in common cuckoo (Cuculus canorus) hosts

Animal Cognition, 2007
Common cuckoos (Cuculus canorus) are obligate brood parasites, laying eggs into nests of small songbirds. The cuckoo hatchling evicts all eggs and young from a nest, eliminating hosts' breeding success. Despite the consistently high costs of parasitism by common cuckoos, great reed warbler (Acrocephalus arundinaceus) hosts sometime accept and other ...

Mechanisms of avian egg-recognition: Do birds know their own eggs?

Animal Behaviour, 1975
Abstract Egg-recognition in birds is generally thought to be weakly expressed since many birds accept a wide diversity of foreign eggs placed in their nests. It has long been believed that even those birds that generally reject foreign eggs (rejector-species) do not practise actual recognition of their own eggs but simply reject any egg-type in the ...

Egg recognition: Its advantage to a butterfly

Animal Behaviour, 1979
Abstract Ovipositing females of the pipevine swallowtail butterfly, Battus philenor, detect the presence of eggs laid by other females on their host plants. The presence of eggs on a plant inhibits oviposition by a female that discovers it. The selection pressure responsible for the evolution and maintenance of discrimination against plants with eggs

Schistosome egg recognition using the top-down search strategy

[1988 Proceedings] 9th International Conference on Pattern Recognition, 2003
A practical implementation of the top-down search strategy has been introduced with its application in schistosome egg recognition from microscope images. The top-down search is implemented by a hierarchy, from the coarse search for a sign of the existence of the object to the fine examination of the texture of the object.

Role of hydrocarbons in egg recognition in the honeybee

Physiological Entomology, 2004
Abstract.  Despite worker‐laid and queen‐laid honeybee eggs having significantly different hydrocarbon profiles, bioassays and chemical supplementation studies show that changing the hydrocarbon profile does not affect egg identity.

Mechanisms of avian egg recognition: Which egg parameters elicit responses by rejecter species?

Behavioral Ecology and Sociobiology, 1982
Some species of North American passerines nearly always reject nonmimetic eggs placed in their nests and have apparently evolved this behavior in response to brood parasitism. Experiments presented here examined the specific egg parameters to which ‘rejecter species’ respond, the relative tolerances rejecters show towards nonmimetic eggs and the degree
