This paper presents the methodology we are applying to rediscover the petroglyphs of the most well-known and studied open-air rock art site on Gran Canaria Island, the Balos Ravine. For this, we are using image analysis with DStretch, which works very well for pigments but not petroglyphs. However, in this case, the use that we give to DStretch is somewhat different; following a series of guidelines and with the help of other tools such as Photoshop, we are obtaining amazing results.
本文介绍了我们重探大加纳利岛(GranCanariaIsland)最著名、且研究最多的露天岩画遗址—巴洛斯峡谷(BalosRavine)岩画所采用的方法。为此，我们使用DStretch进行图像分析，该工具对岩绘画分析效果很好，但对岩刻画分析效果不如前者。因此，在这种情况下，我们对DStretch的应用策略有些不同；我们遵循一系列指导原则，并借助Photoshop等其他工具，取得了相当成功的结果。
