    Adaptive Fine-Grained Sketch-Based Image Retrieval

    The recent focus on Fine-Grained Sketch-Based Image Retrieval (FG-SBIR) has shifted towards generalising a model to new categories without any training data from them. In real-world applications, however, a t...

    FS-COCO: Towards Understanding of Freehand Sketches of Common Objects in Context

    We advance sketch research to scenes with the first dataset of freehand scene sketches, FS-COCO. With practical applications in mind, we collect sketches that convey scene content well but can be sketched with...

    Zone-based keyword spotting in Bangla and Devanagari documents

    In this paper, we present a word spotting system in text lines for offline Indic scripts such as Bangla (Bengali) and Devanagari. Recently, it was shown that the zone-wise recognition method improves word reco...

    Fractional Local Neighborhood Intensity Pattern for Image Retrieval using Genetic Algorithm

    In this paper, a new texture descriptor named “Fractional Local Neighborhood Intensity Pattern” (FLNIP) has been proposed for content-based image retrieval (CBIR). It is an extension of an earlier work involvi...

    A novel feature descriptor for image retrieval by combining modified color histogram and diagonally symmetric co-occurrence texture pattern

    In this paper, we have proposed a novel feature descriptors combining color and texture information collectively. In our proposed color descriptor component, the inter-channel relationship between Hue (H) and Sat...

    Fine-Grained Visual Classification via Progressive Multi-granularity Training of Jigsaw Patches

    Fine-grained visual classification (FGVC) is much more challenging than traditional classification tasks due to the inherently subtle intra-class object variations. Recent works are mainly part-driven (either ...
