Curiosity lies at the heart of the sixteenth-century miscellany books, which served as precursors to the essay genre. Among them, a truly exceptional piece stands out: La silva curiosa by Julián de Medrano, published in 1583. This work pushes the boundaries of curiosity to such an extent that it challenges its classification within the genre of miscellany owing to its unconventional and strange nature. Julián de Medrano, the author of this outlandish work, transforms himself into a character and protagonist, defining himself as an “extremely curious” individual. During his extensive travels, he curates a collection of “curious” epitaphs associated with often comical and peculiar deaths, spanning Latin, Spanish, Portuguese, French, Galician, and Italian. In addition to this, La silva curiosa includes an autobiographical narrative, a precursor to the Gothic genre, in which Medrano recounts unsettling encounters with black magic. This work offers a multifaceted exploration of curiosity, taking it to the extreme by narrating the author’s life experiences driven by a relentless pursuit of the curious, which is synonymous with the bizarre, extraordinary, marvelous, and unexpected. La silva curiosa emerges from a time marked by an almost nihilistic void, as the full force of the Baroque era has not yet arrived, and the ideals of humanism are fading away. It stands as a unique document that unveils an unexpected facet of the concept of curiosity within Spanish Renaissance culture. Full article

This paper presents a new adaptive downsampling technique called elastic downsampling, which enables high compression rates while preserving the image quality. Adaptive downsampling techniques are based on the idea that image tiles can use different sampling rates depending on the amount of information conveyed by each block. However, current approaches suffer from blocking effects and artifacts that hinder the user experience. To bridge this gap, elastic downsampling relies on a Perceptual Relevance analysis that assigns sampling rates to the corners of blocks. The novel metric used for this analysis is based on the luminance fluctuations of an image region. This allows a gradual transition of the sampling rate within tiles, both horizontally and vertically. As a result, the block artifacts are removed and fine details are preserved. Experimental results (using the Kodak and USC Miscelanea image datasets) show a PSNR improvement of up to 15 dB and a superior SSIM (Structural Similarity) when compared with other techniques. More importantly, the algorithms involved are computationally cheap, so it is feasible to implement them in low-cost devices. The proposed technique has been successfully implemented using graphics processors (GPU) and low-power embedded systems (Raspberry Pi) as target platforms. Full article
