- Hilbert-Huang Transform
- License: Freeware

The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear (http://en.wikipedia.org/wiki/Hilbert-Huang_Transform). Learn more about the HHT from the attached pdf. The function plot_hht is best used with spsnip_gui available at http://www.mathworks.com/matlabcentral/fil...objectType=FILE. Essential files: plot_hht.m, emd.m, findpeaks.m Accompanying files: Hum.wav, HHT.pdf.

- Fast 2D Walsh-Hadamard Transform
- License: Freeware

The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 N additions and subtractions. Data sequence length must be an integer power of 2. The inverse transform is the same as the forward transform except for the multiplication factor N x N..

The function implement the 1D Walash Transform which can be used in signal processing,pattern recognition and Genetic algorithms. The Formula of 1D Walsh Transform is defined as : N-1 q-1 ---- -- 1 | | b[i](m)*b[q-1-i](u) W(u) = --- / f(m)| | (-1) ,u = 0,...,N-1 N ---- | | m=0 i=0 where for instance ,A[i] is the ith indices of A.

- Moebius Transform
- License: Shareware

Moebius Transform is a simple application that can easily distort a picture. To use it, just open a JPG or BMP picture and set three points that will be moved to other three points in the new picture.
The rest of the picture will be distorted accordingly, in order to preserve angles. Wait for the process to be done and preview the output in full screen!

- IIS Transform Manager x64
- License: Shareware

Whether you have libraries of content or a steady stream of user-generated content that you want to convert from one video format to another, IIS Transform Manager can help. Transform Manager is an extensible media transform engine that easily enables "watch folder" job submission, queuing, management, integrated media transcoding/transmuxing, and batch-encryption of on-demand audio and video files.
Transform Manager x64integrates directly with Microsoft Expression Encoder 4 Service Pack 2 (SP2) to allow you to queue multiple encoding jobs in specified input folders ("watch folders") on your server, process them per a job template created from a set of pre-defined rules ("tasks"), and then deliver them directly to specified output folders.

- Application Virtualization MSI Compat Transform
- License: Shareware

The App-V MSI Compat Transform is used to make App-V 4.5 Sequencer generated MSIs adaptable for App-V 4.6 Client. Running an .msi generated by the in App-V 4.5 sequencer produces a load/install error when trying to run it on an App-V 4.6 Client.
Running a Windows Installer (.msi) file generated by the App-V 4.5 Sequencer produces a load/install error when trying to run it on an App-V 4.6 client. You will see the following message: "This package requires Microsoft Application Virtualization Client 4.5 or later". You can use the transform file launchcondition.mst to successfully run a Windows Installer file generated by the App-V 4.

- 1D Fast Fourier Transform
- License: Freeware

The Fourier Transform is a powerful tool allowing us to move back and forth between the spatial and frequency domains. Many of our explanations of key aspects of signal processing rely on an understanding of how and why a certain operation is performed in one domain or another. This applet helps students feel comfortable with these explanations, helping to build a strong intuitive grasp of how signals in one domain correspond to signals in the other.
Students can load scanlines from common image patterns and see that scanline's Fourier Transform in real-time. For example, they can load the scanline of a standard test image to note how most of the energy is concentrated at low frequencies -- a key to why low-pass filtering doesn't render an image unintelligible.
