Prediction of the Weight of Quail Eggs Through Shape Features and Spectral Indices

Abstract

In the present work, a method for indirect determination of the weight of Japanese quail eggs is proposed, taking into account changes in their internal properties. Visual data and transmission spectra is used. Shape features and spectral indices are selected and applied. It has been found that egg weight M can be predicted by the volume V of eggs and the spectral index GLI, M=f(V,GLI). The resulting model has a coefficient of determination R2=0,89, low error values, up to 3%. Mean square error MSE=0,03 and root mean square error RMSE=0,2. The results obtained can be used to indirect determination the weight of Japanese quail eggs when incubated, packaged.

Application of Classification Techniques in the Analysis of External Characteristics of Eggs

“…Measurements were taken on days 1, 7, 14, and 21 of storage. The measurement system presented in [12] was used to obtain digital images, spectral and dielectric characteristics. The system is expanded with a lighting module and a single-board microcomputer with a capacitor cell included.…”

“…Spectral characteristics of the quail and hen eggs were obtained, which was done by converting the values of the LMS model into transmittance spectra in the VIS region, in the range 390-730nm, according to the mathematical dependences presented in [35]. Shape indexes d, D, A, P, Ai, V, Amr, Kv, Kf, K1, c1, r1, KA, KAM according to [12] have been determined. Spectral indices REI, PTI, CTI, TVI, G, NExG, NGRDI, RGBVI, GLI, VARI, ExG according to [5,7] are determined.…”
