Real-time content-aware image resizing using reduced linear model
Roberto Gallea, Edoardo Ardizzone, Roberto Pirrone · 2010
In this paper is presented an effective and efficient method for content-aware image resizing. It is based on the solution of a linear system where each pixel displacement (compression or expansion) is determined in dependence of the visual relevance of the pixel itself. The linear nature of the model allows real-time application of the method even for large images. This fully automatic approach can be also improved by interactively providing cues such as geometric constraints and/or manual relevant object labeling. The results have proven that the presented method achieves results comparable to existent strategies, while improving efficiency.
