In this paper, we propose a novel content-aware image mosaic approach based on image saliency. The image saliency is used in the whole process of creating an image mosaic with variable size tiles, while a novel energy map is proposed by combining Neighborhood Inhomogeneity Factor and Graph-Based Visual Saliency. The target image is divided into small tiles with variable sizes based on the energ...

Reconstruction of an image (or shape or wavefront) from measurements of the derivatives of the image in two orthogonal directions is a common problem. We demonstrate how a particular reconstructor, commonly referred to as the Fried algorithm, can be used with megapixel derivative images to recover the original image. Large datasets are handled by breaking the derivative images into smaller tile...

The Projection-Based Image is a new banknote security feature that projects a desired image when an array of microlenses embossed into the banknote substrate is exposed to a light source. The feature is designed computationally to make the projected image difficult to discern by inspection of the lens structures, and to accommodate a range of light sources, allowing wide accessibility to users ...

Image retrieval based on color, texture and shape is an emerging and wide area of research scope. In this paper we present a novel framework for combining all the three i.e. color, texture and shape information, and achieve higher retrieval efficiency using dominant color feature. The image and its complement are partitioned into non-overlapping tiles of equal size. The features drawn from cond...

the art of qajar period includes many unique features and themes. one of the most exceptional features of qajar artworks (painting on tiles) is women motifs depicted at semiprivate and private spaces, at houses of nobilities, and palaces. qajar women in these paintings interact with foreign women’s identity and they have shown a new face of iranian women. the archi-myth of qajar period is inclu...
