“…These measurements of biological activity during fruit development are the result of physicochemical variations that occur inside the cells, and such behavior of biological activity reduction may be caused by metabolic, enzymatic and respiratory activity that occur during the ripening process. Kumari & Nirala (2016) used the Biospeckle laser to differentiate fresh from damaged areas in apples. They found that the level of biological activity in both areas decreased as the maturation process evolved, which corroborates the results found in our paper.…”

“…Among the many image processing methods, the generalized differences method (GD) has good qualitative results (Kumari & Nirala, 2016). The GD algorithm calculates the absolute sum of the intensity differences between an image and its subsequent one, identifying the luminous intensity of each component pixel, thus resulting in a new image, which the pixels with different intensities highlighted (Minz & Nirala, 2013).…”

The objective of this study was to evaluate the response of biological activity measured by the Biospeckle Laser technique applied to mangoes (Mangifera indica L.) subjected to mechanical damage at different stages of maturation. The tests were carried out twice a week for twenty-one days, and 40 mangoes of the variety Tommy Atkins were used. The procedure was divided into two stages: the first simulated the impact on fruits, and in the second stage, the laser light was applied to the impacted area. After laser application, the images of all fruits were submitted to graphic processing, in order to obtain maps of biological activity of the fruits. The Biospeckle laser technique associated with image analysis allowed the identification of distinct biological activity levels in the mangoes, certifying its potential application as a non-destructive test tool, in the monitoring of biological activity in fruit samples.

In the present paper we have used a noncontact and non-destructive laser biospeckle technique for detection, differentiation and mapping of noninfected region of a fresh Indian gooseberry and bright yellow and blue regions of a blue mold disease infected Indian gooseberry (Emblica Officinalis G.) for the first time to the best of our knowledge. Existing image processing algorithms such as Co-occurrence Matrix, Inertia Moment, Absolute Value of Differences, Fujii, Inverse Fujii, Alternative Fujii, Parameterized Fujii, Generalized Difference (GD), Parameterized GD, Alternative GD (AGD), and three newly proposed algorithms namely Cubic Absolute Difference (CAD), qFujii, Parameterized Geometrical Mean of Temporal Difference (PGMTD), have been used for this purpose. It is concluded that for detection and differentiation, CAD provides the highest value of bioactivity difference between non-infected & bright yellow (3463.81), non-infected & blue (4250.29) and bright yellow & blue (786.48) regions where as qFujii and Fujii give better results for mapping apart from detection and differentiation of the different regions. PGMTD, Alternative Fujii, Parameterized Fujii and AGD also provide quite acceptable results for detection, differentiation and mapping of the three regions. In addition, it is also found that bioactivity decreases when Indian gooseberry is infected with the pathogen and the infected blue region has lowest bioactivity compared to the infected bright yellow region.

The drying time of adhesives such as Fevicol SH, Fevicol MR, Dendrite white and Bulbond after coating separately on the three plywoods, namely Archidply, Centuryply and Greenply, has been studied non-destructively using the dynamic speckle technique. The time history of the speckle pattern, the co-occurrence matrix, 3D graphs and line profiles of images from the time history of the speckle pattern along with 3D trajectory plots have been used for qualitative analysis whereas the inertia moment, absolute value difference, SM index and autocovariance have been used for quantitative analysis. The gray-level co-occurrence matrix has been used for the first time to study the textual parameters of adhesive coated on plywoods during drying. The average drying time of adhesive is a maximum for Bulbond on Archidply (357.25 ± 1.49 min) and a minimum for Dendrite white on Greenply (90.75 ± 2.36 min). Comparative studies among the results obtained for all the four adhesives on the three plywoods reveal that Dendrite white adhesive is the best among the adhesives because it takes the shortest time to dry on all the plywoods, and Greenply is the best among all the plywoods because drying is fastest on it for all the adhesives. Furthermore, it is also concluded that the best plywood and the best adhesive may be decided by knowing the remnant activity.
