In the present paper intensity-based algorithms have been applied to differentiate the bruised and fresh regions of an Indian apple through biospeckle technique during its 9 day shelf life. Existing algorithms such as the co-occurrence matrix, inertia moment, absolute value difference, generalized difference, parameterized Fujii, biospeckle activity (BA) value, granulometric size distribution (GSD) and grey-level co-occurrence matrix (GLCM), as well as three new proposed algorithms namely parameterized generalized difference, alternative generalized difference (AGD) and parameterized global average Fujii, have been used for qualitative and quantitative analysis. Co-occurrence matrix and activity level spectral maps have been used for qualitative analysis, whereas mean activity plots, curve of the BA index, GSD plots and texture features have been used for quantitative analysis. The experimental results suggest that overall difference in biospeckle activity between the bruised and fresh regions is maximum for the inertia moment method (521.99). Of the three proposed algorithms AGD gives the maximum overall difference in biospeckle activity (42.35). In addition, the BA value and parameters of the GLCM have also been applied for the first time to distinguish between the bruised and fresh regions of an Indian apple, and it is concluded that both the methods may be used for good differentiation between the bruised and fresh regions of apples.

“…Inertia Moment (IM) is a routine method which has been used for activity evolution of fruits during their shelf life [13], quality evaluation of orange fruits [14] and to study the transient process in ice cream [15] quantitatively. The qualitative methods such as generalized difference (GD) and the Fujii method present the spectral maps for different activities of biological samples [16,17]. The IM method has been applied to the frequency response of a biological sample such as a bean seed contaminated by fungi [18] and the seed drying process [19].…”

Our present work aims to study the physiological changes of chemically treated fresh-cut potato tubers and then to correlate such changes with the results of the non destructive and non invasive laser biospeckle technique. The effect of chemically treated (citric acid (CA-0.5% and 1.0%) and citric acid + sodium chloride (CS-0.5% and 1.0%)) fresh-cut potato tubers on physiological activities such as the respiration rate and weight loss at cold storage has been studied for eight consecutive days. In addition, biospeckle recording has been carried out for eight consecutive days for all the chemically treated samples and from captured images, and the numerical results (inertia moment (IM)) with and without frequency filtering have been obtained. A comparatively higher respiration rate and lower weight loss is observed for CS treated samples than that of CA treated samples. The results of the IM obtained with the exclusion of the higher frequency show a similar nature to the respiration rate and also, separations of the respiration curves at two concentrations for both the treated samples were well correlated with the IM curves. The concentration effect for both the treatments on the IM value with the exclusion of lower frequencies has also been presented. Thus the IM method with filtration of particular bands is able to separate the different physiological phenomena with one another and is also able to differentiate the chemical effect on the samples.

“…Since microorganism activity makes the optical properties of the medium change, there is a causal link between microorganism activity and speckle pattern dynamics (speckle pattern activity). This causal link has been exploited for motility characterization of parasites [14], bacteria [4,[15][16][17][18], bovine spermatozoa [19], activity of fungi [20][21], seeds [22][23], cells [24] and fruits [25].…”

Abstract-We monitor bacterial spreading in time using dynamic laser speckle technique. An experimental set-up was designed and implemented in order to minimize the exposure time of the sample to the laser radiation. This schema allows widening the assessment of bacterial responses using biospeckle dynamics as it makes possible an evaluation of the acceleration or delay, inactivation or stimulation of radial growth of bacterial cultures due to continuous or instantaneous illumination with laser light.
