Offline MODI Character Recognition Using Complex Moments

AbstractThe varying writing style and critical representation of characters in Indian script makes Handwritten Optical Character (HOCR) challenging and has attracted researchers to contribute in this domain. ‘MODI’ Script had cursive type of writings in Devanagari, Marathi where large amount of historical documents were available and need to be digitally explored. The principal objective of this research work is to describe efficiency of Zernike Complex moments and Zernike moments with different Zoning patterns for offline recognition of handwritten ‘MODI’ characters. Every character was divided in six zoning patterns with 37 zones. Geometrical shapes were used to create zoning patterns. The work was resulted in 94.92% correct recognition rate was achieved by using Zernike moments and 94.78% by using Zernike complex moments with integrated approach for heterogeneous zones

A Novel Class of Pyrazoline Analogue of Combretastatin-A4 (CA-4): Synthesis Characterization and in-vitro Biological Testing

A series of pyrazoline bridged combretastatin analogues were designed and synthesised from their precursor chalcone analogues, and all these compounds were ascertained by IR, 1H NMR, and mass spectral analysis. Subsequently, all these compounds were evaluated for anticancer activities against breast cancer (MCF-7) and normal Vero (Monkey Kidney) cell lines, and five selected compounds from the series were evaluated against Hela (Human Cervical), MDA-MB-231 (Breast), and A-549 (Lung cancer) cell lines using the Sulforhodamine B (SRB) assay method. Compounds 3a, 6a, 6e, 5b, 7a, 5a, and 7d were found to be the most potent in the series, with a GI50 value of 10 to 30 M in the MCF-7 cell line. Moreover, the same compounds 6a and 7a showed remarkable cytotoxicity against the A-549 (Lung) cell line with a GI50 value ranging from 10 to 30 M, while compound 3a displayed moderate cytotoxicity against the Hela (Human Cervical) cell line. All these compounds were found nontoxic to the Vero (Monkey Kidney) normal cell line
