In this paper we review shapelets, an image manipulation algorithm, which we employ to adjust the point-spread function (PSF) of galaxy images. This technique is used to ensure the image in each filter has the same and sharpest PSF, which is the preferred condition for detecting AGNs using multi-filter imaging data as we demonstrated in Paper I of this series. We apply shapelets on Canada-France-Hawaii Telescope Legacy Survey Wide Survey ugriz images. Photometric parameters such as effective radii, integrated fluxes within certain radii, and color gradients are measured on the shapelets-reconstructed images. These parameters are used by artificial neural networks (ANNs) which yield: photometric redshift with an rms of 0.026 and a regression R-value of 0.92; galaxy morphological types with an uncertainty less than 2 T types for z<=0.1; and identification of galaxies as AGNs with 70% confidence, star-forming/starburst (SF/SB) galaxies with 90% confidence, and passive galaxies with 70% confidence for z<=0.1. The incorporation of ANNs provides a more reliable technique for identifying AGN or SF/SB candidates, which could be very useful for large-scale multi-filter optical surveys that also include a modest set of spectroscopic data sufficient to train neural networks.2013AJ....146...87Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/87CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/317 : The CFHTLS Survey (T0007 release) (Hudelot+ 2012)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/ApJS/186/427 : Detailed morphology of SDSS galaxies (Nair+, 2010)J/A+A/461/81 : Galaxy clusters in the CFHTLS (Olsen+, 2007)J/AJ/134/579 : SDSS DR3 morphologically classified galaxies (Fukugita+, 2007)J/AJ/128/163 : Galaxy morphological classification (Lotz+, 2004)http://terapix.iap.fr/cplt/T0006-doc.pdf : The CFHTLS T0006 releasehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/146/87https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/146/87http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/146/87https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/146/87https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/146/87http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/146/87GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/146/87/table3 (The catalog of results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/146/87/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/146/87/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/146/87/table3?GETtext/xml+votable180.050000true333.54010010.82575650.0055555555555555564/1191 5/4758 4759 6/19021 19023 19025 19026 19027 19028 19030 19031 19047 19053 19153 19156 19157 19158 19208 19232 19240 19242https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/146/87?format=asciiInfraredOpticaldefaultJ/AJ/146/87/table3The catalog of resultsrecnoRecord number assigned by the VizieR team.
