In this paper, we describe a new technique for the automatic orientation of bedding in drill core from digital images. Images are planar pictures of the drill core, and we show that it is possible to determine layer orientation without rotating the core on the full circumference. More precisely, we show that angle information can be extracted by applying(More)
Digital signal processing is commonly used in Geophysics. Methods combining core sample physical property measurements with image analysis are beginning to emerge. In this paper, we describe a digital processing method applied directly to core sample images. Our approach uses a number of time-frequency and scale-frequency transformations as well as(More)
