This descriptor, called IDSC-wFW (a weighted Fourier and wavelet-like descriptor based on inner distance shape context), first rewrites shape histograms of IDSC descriptors, changing the histogram belonging to a point to the histogram belonging to a field, and sets the histogram of a field as a one-dimensional signal, then transforms this one-dimensional signal by using a Fourier transform and a transform similar to Haar wavelet. Finally, the two transform results are linearly combined to form a new descriptor. This new descriptor requires only a distance-based measure method during the matching stage. Experimental results on three well-known databases show that this new descriptor not only obtains accurate retrieval results but also runs fast.<\/jats:p>","DOI":"10.3390\/sym11050693","type":"journal-article","created":{"date-parts":[[2019,5,20]],"date-time":"2019-05-20T11:05:07Z","timestamp":1558350307000},"page":"693","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A Weighted Fourier and Wavelet-Like Shape Descriptor Based on IDSC for Object Recognition"],"prefix":"10.3390","volume":"11","author":[{"given":"Yan","family":"Zheng","sequence":"first","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baolong","family":"Guo","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheng","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunyi","family":"Yan","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1016\/S0031-2023(97)00122-2","article-title":"A survey of shape analysis techniques","volume":"31","author":"Loncaric","year":"1998","journal-title":"Pattern Recognit."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1911","DOI":"10.1016\/j.patcog.2006.12.005","article-title":"Shape retrieval using triangle-area representation and dynamic space warping","volume":"40","author":"Alajlan","year":"2007","journal-title":"Pattern Recognit."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"286","DOI":"10.1109\/TPAMI.2007.41","article-title":"Shape classification using the inner-distance","volume":"29","author":"Ling","year":"2007","journal-title":"IEEE Trans.
