Representative Image Thumbnails for Good Browsing

Representative image thumbnails: automatic and manual

“…2 The Extract blur map block results in a two dimensional thumbnail resolution blur map with estimates of the amount of blur at each thumbnail pixel and the block Apply space-varying filter applies a filter based on this blur map. This local computation accounts for depth-of-field as well as other undesired blurs.…”

“…1 Although this process prevents aliasing and preserves the image composition, it loses information about image quality and high spatial frequency textures. 2 Several recent papers offer interesting, non-traditional approaches to reducing image size. [3][4][5][6] Even though the algorithms differ, they each modify image composition while resizing, generating better thumbnails.…”

“…The papers address images with different types of content such as web pages, 3 documents 5 and photographs. 4,6 Automatic thumbnails that we previously developed 2 do not modify the image composition, but rather better reflect the image quality of the originals. Current, standard thumbnails do not distinguish between high and low quality originals.…”

Image thumbnail based on fusion for better image browsing

“…Pixel-based Down-Sampling with Anti-aliasing Filter (PDAF) is one of the common methods to generate image thumbnail [3]. There are two main stages involved in PDAF.…”

Thumbnail Images Using Resampling Method

“…The standard thumbnails introduced in [3] do not modify the image composition but better reflects the image quality of the originals. The New thumbnails provide a quick, natural way for users to identify images of good quality at the same time that they select images with desired subject matter.…”
