Identification of double-yolked duck egg using computer vision
The double-yolked (DY) egg is quite popular in some Asian countries because it is considered as a sign of good luck, however, the double yolk is one of the reasons why these eggs fail to hatch. The usage of automatic methods for identifying DY eggs can increase the efficiency in the poultry industry by decreasing egg loss during incubation or improving sale proceeds.

متن کاملChanges During Incubation Within Double-Yolked Duck (Anas platyrhynchos domesticus) Eggs: Yolk Position, Mortality, Hatchability and the Importance of an Optimal Egg Size
Double-yolked (DY) and single-yolked (SY) duck eggs (n = 1318 for both) were candled and weighed on Days (d) 2, 8, 12, 15, 19, 22 and 25 of incubation and yolk/embryo position was recorded on d2, d8 and at post-mortem. From d8 only eggs with live fertile yolk(s) remained in the incubator. On d2, 99.39% of yolks in DY eggs were in the adjacent position and by d8 yolk positions changed to paralle...
متن کاملDouble and Single Yolked Duck Eggs: Their Contents and Dimensions Compared and the Mechanical Stimulation Hypothesis for Albumen Secretion Is Supported
The external dimensions, weight and contents (yolk, albumen, shell) of Double Yolked (DY) and Single Yolked (SY) eggs of the duck (Anas platyrhynchos domesticus) were measured and compared. The yolks in DY eggs did not differ in weight (p = 0.144), although each double yolk was significantly lighter than the yolk of a SY egg (p<0.001). DY albumen weight was below that expected of a SY egg of co...
متن کاملp63 is more sensitive and specific than 34βE12 to differentiate adenocarcinoma of prostate from cancer mimickers
