A voltammetric electronic Tongue consisting of novel metal base electrode array for classification of Amylose present in rice samples was developed. The electrode array consisting of Gold, Palladium, Platinum, Rhodium and Iridium as working electrode has been used for transforming information of Amylose content in rice into electric signal. The electrodes output shows different pattern of electrical signal for rice samples that have different Amylose percentage. experiments were carried out on four different rice samples having Amylose content in low, medium and high level. Principal Component Analysis (PCA) was used for visual inspection of data set. Classification was performed by statistical method. A fair discrimination was obtained and this rapid, low-cost method may be useful for prediction of Amylose percentage in rice for breeding and quality perspective. © 2011 Ieee.

Proposed here is a simple and effective method for identification of connected grains in an image. The grains considered here are the whole lentil grains which are circular in shapes. These circular shapes can be considered as convex polygons. When two or more such convex polygons are connected or partially overlapped, there are concave regions along the boundary line of the connected region. Such concave regions form the convex deficiencies for the convex hull of the connected or overlapped grains. Finding the number convex deficiencies in the convex hull of connected object boundaries allows us to identify whether connected component is formed by connecting two or more objects or grains. Also, it allows us to exactly count the number of connected objects and simplifies the finding the segmentation boundaries. The method is simple, fast and gives good accuracy of counting connected grains without actually segmenting the connected grains. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Jasmine is one of the important commercial traditional flower crops of India. It plays an important role in religious offerings, social and cultural activities of India. It is also used for the production of essential oils in the form of 'concrete' and 'absolute' which are used in cosmetics and perfumery industries. Fully open flowers contain maximum fragrance and needs to be collected for concrete extraction. India earns crores of foreign currency every year through export. Being an export commodity, ideal blossoming time and quality testing of jasmine flowers are extremely crucial matters in exportation of flowers and concrete. The quality evaluation is human dependent and their sensory organs may give different results at different points of time, as well as the result may vary from the one evaluator to another since no two person can perceive a thing identically. The results may also vary based on the physiological climatic and many other allied conditions. In a nutshell, the evaluation methodology is highly subjective and lacks the precision of an automated machine. Hence, there is a need for an automated, portable, low-power, easy- to use and reliable machine, which can evaluate quality objectively and repetitively, so that it can assist the Floriculture Industry, research laboratories and flower exporters for final evaluation of jasmine flower and its concrete quality. A handheld electronic Nose system has been developed which can be used to monitor the volatile emission pattern of jasmine flower and concrete on the basis of sensor outputs. This paper presents a study where, first, the selection of appropriate sensors was carried out based on sensitivity with the major aroma-producing chemicals of jasmine flower and concrete. Then, this sensor array was exposed to flowers at its different stage of maturity that were collected from the farmer's field at Sathyamangalam, erode district, Tamil Nadu in India and to concrete of different species.

Handwritten text is potentially the most powerful and conventional means of personal authentication in Human Computer Interaction, with applications to be found in document analysis, deception detection, banking and many other areas. Handwriting is a complex perceptual motor task generating linguistic information. Characters reflect shape distinction needed to perceive different phonetic information of words. In this paper, we have tried to emphasize the role of perception and cognition in identifying unique characteristics of handwriting of any person to screen out deceptive and true statements as a computational model in the areas of Pattern Recognition and Human Computer Interaction. The paper reports the prototype development of a decision support system based on handwriting behavior analysis.

electronic Nose (e-Nose) has been found suitable to assess quality of many agricultural and food products as well as this have immense potential in biomedical applications for early detection of diseases. However, the major challenge here is to develop a generic e-Nose platform that can be used in various application domains by the researchers. Since apart from sensors and electronic components, an e-Nose involves electromechanical parts for odour delivery to the sensors this is extremely difficult to develop a small, portable, low power device that would be rugged enough for continuous field usage. This paper describes a generic handheld e-Nose platform that is rugged enough for field usage and suitable for applications in various domains like Agricultural and Horticultural produces and biomedical applications. The e-Nose was first developed for applications in the tea industry to solve the following two problems:. Assessment of quality of tea based on its aroma. Detection of optimum Fermentation time during tea manufacturing process Based on the preliminary success in the tea domain, effort was made to make this platform generic so that various other domains may also be served. effort towards miniaturization, reduction in power consumption, convenience of use were also given priority and finally we came out with a perfectly handheld, battery operated and field deployable generic e-Nose platform. This generic platform is in use by the researchers in domains like tea, different spices, jasmine, cheese ripening, waste water quality detection, early detection of diabetes, etc. This generic handheld e-Nose platform is developed on a 16-bit microprocessor platform, experimental data are stored in a SD Memory Card, user-input is through Touch Screen interface and results are displayed onto a Graphics display. A rechargeable battery pack powers the system continuously at least for 10 hours and miniature pump and valve are used for the odour delivery mechanism. A sensor ar

Character recognition (Printed and Handwritten) system has become an extremely useful tool in Human Computer Interaction. Handwriting is a complex perceptual motor task generating linguistic information. Characters reflect shape distinction needed to perceive different phonetic information of words. We have explored 'perceptual processes' of character recognition for developing a cognitive model. especially, we tried to extract the Perceptual Anchorage Points in the character. An experiment was performed to identify Perceptual anchorage points in a character both for handwritten as well as printed character of different Bangla script fonts including fonts used in Bangladesh. A set of important points and shapes has been found in the experiment. It is noted that deletion of these regions from characters greatly reduces the human cognition of characters. © 2012 Springer-Verlag.

Representation of 2D frameless visual space as neural manifold and its modelling in the frame work of information geometry is presented. Origin of hyperbolic nature of the visual space is investigated using evidences from neuroscience. Based on the results we propose that the processing of spatial information, particularly estimation of distance, perceiving geometrical curves etc. in the human brain can be modelled in a parametric probability space endowed with Fisher-Rao metric. Compactness, convexity and differentiability of the space is analysed and found that they obey the axioms of G space, proposed by Busemann. Further it is shown that it can be considered as a homogeneous Riemannian space of constant negative curvature. It is therefore ensured that the space yields geodesics into it. Computer simulation of geodesics representing a number of visual phenomena and advocating the hyperbolic structure of visual space is carried out. Comparison of the simulated results with the published experimental data is presented. © 2020, CC-BY-NC-SA.

This paper describes a new approach to english to Bangla translation. The english to Bangla Translator was developed. This system (BANGANUBAD) takes a paragraph of english sentences as input sentences and produces equivalent Bangla sentences. The BANGANUBAD system comprises a preprocessor, morphological recursive parser, semantic parser using english word ontology for context disambiguation, an electronic lexicon associated with grammatical information and a discourse processor. It also employs a lexical disambiguation analyzer. This system does not rely on a stochastic approach. Rather, it is based on a special kind of amalgamated architecture of transformer and rule-based NLe architectures along with various linguistic knowledge components.

Quality of black tea is generally assessed using organoleptic tests by professional tea tasters. They determine the quality of black tea based on its appearance (in dry condition and during liquor formation), aroma and taste. Variation in the above parameters is actually contributed by a number of chemical compounds like, Theaflavins (TF), Thearubigins (TR), Caffeine, Linalool, Geraniol etc. Among the above, TF and TR are the most important chemical compounds, which actually contribute to the formation of taste, colour and brightness in tea liquor. estimation of TF and TR in black tea is generally done using a spectrophotometer instrument. But, the analysis technique undergoes a rigorous and time consuming effort for sample preparation; also the operation of costly spectrophotometer requires expert manpower. To overcome above problems an electronic Vision System based on digital image processing technique has been developed. The system is faster, low cost, repeatable and can estimate the amount of TF and TR ratio for black tea liquor with accuracy. The data analysis is done using Principal Component Analysis (PCA), Multiple Linear Regression (MLR) and Multiple Discriminate Analysis (MDA). A correlation has been established between colour of tea liquor images and TF, TR ratio. This paper describes the newly developed e‐Vision system, experimental methods, data analysis algorithms and finally, the performance of the e‐Vision System as compared to the results of traditional spectrophotometer.
