    FreeCAD is a free and open-source application that can work with the DWG files by using the proprietary ODA File Converter for .dwg and .dxf files from the Open Design Alliance (ODA). [55] The ODA also provides a freeware stand-alone viewer for .dwg and .dgn files, ODA Drawings Explorer, which runs on Windows, Linux, and Mac OS X.

  3. Discrete wavelet transform - Wikipedia

    en.wikipedia.org/wiki/Discrete_wavelet_transform

    In numerical analysis and functional analysis, a discrete wavelet transform (DWT) is any wavelet transform for which the wavelets are discretely sampled. As with other wavelet transforms, a key advantage it has over Fourier transforms is temporal resolution: it captures both frequency and location information (location in time).

    Drawing Standards File .dws: Using the CAD Standards feature of AutoCAD, a Drawing Standards File may be associated to any .dwg or .dwt file to enforce graphical standards. Drawing Interchange Format .dxf: The .dxf format is an ASCII representation of a .dwg file, and is used to transfer data between various applications. [34]

  6. The dual tree hypercomplex wavelet transform (HWT) developed in [9] consists of a standard DWT tensor and 2 m -1 wavelets obtained from combining the 1-D Hilbert transform of these wavelets along the n-coordinates. In particular a 2-D HWT consists of the standard 2-D separable DWT tensor and three additional components: H x {ψ(x) h ψ(y) h ...

    en.wikipedia.org/wiki/ZWCAD

    ZWCAD is compatible with widely used 2D CAD drawing formats (such as DWG, [6] DWT, DXF, DWF) and can directly read and save common graphics information. In addition, ZWCAD's interface and usage are similar to those of other 2D CAD software.

    JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
