The application of fractal geometry requires estimation of the fractal features. The fractal dimension and fractal length are found effective to analyze and measure image features, such as texture, resolution, etc. This paper proposes a new wavelet\u2013fractal technique for image resolution enhancement. The resolution of the wavelet sub-bands are improved using scaling operator and then it is transformed into texture vector. The proposed method then computes fractal dimension and fractal length in gradient domain which is used for resolution enhancement. It is observed that by using scaling operator in the gradient domain, the fractal dimension and fractal length becomes scale invariant. The major advantage of the proposed wavelet\u2013fractal technique is that the feature vector retains fractal dimension and fractal length both. Thus, the resolution enhanced image restores the texture information well. The texture information has also been observed in terms of fractal dimension with varied sample size. We present qualitative and quantitative analysis of the proposed method with existing state of art methods. <\/jats:p>","DOI":"10.1142\/s0218126623500354","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T16:00:30Z","timestamp":1659024030000},"source":"Crossref","is-referenced-by-count":7,"title":["Fractal Feature Based Image Resolution Enhancement Using Wavelet\u2013Fractal Transformation in Gradient Domain"],"prefix":"10.1142","volume":"32","author":[{"given":"Shyo Prakash","family":"Jakhar","sequence":"first","affiliation":[{"name":"Department of Computer and Communication Engineering, Manipal University Jaipur, Rajasthan 303007, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1150-2690","authenticated-orcid":false,"given":"Amita","family":"Nandal","sequence":"additional","affiliation":[{"name":"Department of Computer and Communication Engineering, Manipal University Jaipur, Rajasthan 303007, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arvind","family":"Dhaka","sequence":"additional","affiliation":[{"name":"Department of Computer and Communication Engineering, Manipal University Jaipur, Rajasthan 303007, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bojie","family":"Jiang","sequence":"additional","affiliation":[{"name":"Xin Hua Hospital Affiliated to Shanghai, Jiao Tong University School of Medicine, Shanghai, P.
