In this volume, the varied histories of Australian rock art research from different parts of the country are explored not only in terms of key researchers, developments and changes over time, but also the crucial role of First Nations people themselves in investigations of this key component of their living heritage. Through the 1900s, there was also growing interest in Australian rock art from researchers across the globe, leading many to visit or migrate to Australia to undertake rock art research. Since then, Australian rock art has been researched from various perspectives, including that of Traditional Owners, custodians and other community members. Through the 1900s an impressive body of research on Australian rock art was undertaken, with dedicated academic study using archaeological methods employed since the late 1940s. Since the late 1700s, people arriving in Australia have been fascinated with the rock art they encountered, with detailed studies commencing in the late 1800s. The art reflects and expresses changing experiences within landscapes over time, spirituality, history, law and lore, as well as relationships between individuals and groups of people, plants, animals, land and Ancestral Beings that are said to have created the world, including some rock art. First Nations people have been marking these places with figurative imagery, abstract designs, stencils and prints for tens of thousands of years, often engaging with earlier rock markings. The software, written in Python, is provided as a stand-alone executable program for Windows, for broader diffusion, and as open-source code, which can therefore be adapted to the evolving needs of the community.Īustralia has one of the largest inventories of rock art in the world with pictographs and petroglyphs found almost anywhere that has suitable rock surfaces – in rock shelters and caves, on boulders and rock platforms. There is no need for complex tuning at any point during the procedure, which lasts a few minutes at most, while a posteriori cleaning of the produced document is minimal. At this step, binary pixel classification is performed either by logistic regression, support vector machine, or k-nearest neighbours, possibly including confident learning. The researcher can then take advantage of supervised machine learning algorithms to isolate painted figures. The most subtle colour variations will be better perceived in some of these newly produced, contrasted, false-coloured images. The decorrelated data, previously stretched and scaled to fit the RGB space, are then converted into various colour spaces (selected from among the most popular): XYZ, HLS, HSV, LAB (CIELAB), Luv, CMY(K), YCrCb, and YUV. the covariance matrix of the new channels equals the identity matrix). These transformations produce different arrangements of the colour information, which nevertheless share some important properties (e.g. In contrast with the approaches previously developed specifically for rock art, several data-whitening algorithms are used at this step: (regular) principal component analysis, zero-phase component analysis, Cholesky decomposition, and independent component analysis. The three RGB colour channels of the digital image are first decorrelated and then stretched, a well-known technique used by remote-sensing specialists for over thirty years. The present study proposes a new software program to help researchers identify rock paintings from digital images, rapidly producing high-quality documentation, in a user-friendly way.
