classdef nvis < nvisBase
%nvis visualizes 2D slices from higherdimensional data
% NVIS(I) opens a UI that displays one 2D slice from the input
% matrix I with N dimensions (N>2). Sliders allow to navigate thorugh
% the remaining, non-singleton dimensions. The windowing of the
% colormaps can be dynamically changed by pressing the middle mouse
% button on the image and moving the mouse up/down (center) or
% left/right(width). ROIs can be drawn to measure Signal to Noise
% ratio in image data.
%
% NVIS(I1, I2): Data from the matrices I1 and I2 are overlaid
% by adding (default) the RGB values attributed by the individual
% colormaps. The windowing for the second image can be adjusted by
% using the left mouse button. Image sizes must not be identical, but
% for dimensions, where the size is different, one matrix must be of
% size one.
%
% Usage
%
% Values in the lower left show the array indices of the datapoint
% under the cursor as well as the matrix-values at that location. In
% case of complex data, the value is shown in the current complex
% mode.
% Colorbar button in the matlab figure-toolbar can be used to show
% adapting colorbars.
% <- and -> change the dimensions that are shown along the image
% dimensions. Initially, dimensions 1 and 2 are shown. By presing <-
% / -> both are decreased/increased by 1, wrapping where necessary.
% 'Run' starts a timer which loops through the image dimension
% selected by the radio button. 'SaveImage' save the currently
% visible image to file, 'SaveVideo' saves the running animation as a
% video file (.avi or .gif)
% The crosshair button creates a circle in the current image and the
% 'Plot' button opens an external window that shos the behavior of
% the data through that point along different dimensions of the input
% matrix. Continuous updating of the data shown in the external plot
% can be switched on or off using the 'Update' button.
%
% Name-Value-Pairs
%
% Name------------Value-------Descripton-----------------------------
%
% 'CW' 1x2 double Initial values for center and width.
% For two input matrices, Value must be
% 2x2 matrix, or values are applied to
% both.
% 'Colormap' Nx3 | char initial colormaps for the image. The
% user can either supply a custom
% colormap or chose from the available
% colormaps. Default is gray(256). For
% two input matrices, value must be 1x2
% cell array. Default is {'green',
% 'magenta'}. More colormaps are
% available if 'colorcet.m' is found on
% the MATLAB path (Peter Kovesi,
% https://peterkovesi.com/projects/colourmaps/)
% 'Contrast' char redundant NVP, will be removed in
% future versions.
% 'Overlay' int inital overlay mode for two input
% matrices (1: add (default), 2:
% multiply)
% 'ComplexMode' int For complex data, chooses the initially
% displayed complex part (1: magnitude
% (default), 2: phase, 3: real part, 4:
% imaginary part).
% 'AspectRatio' 'image' the displayed axes have the same aspect
% ratio as the input matrix for that
% slice, i.e. pixels will be squares.
% 'square' The displayed axes always have a square
% shape.
% 'Resize' double uses 'imresize' to resize the currently
% displayed slice by the given value.
% 'Title' char title of the figure window
% 'Position', 1x4 int Position of the figure in pixel
% 'Unit' char physical unit of the provided image
% data. For two input matrices, value
% must be 1x2 cell array, or both are
% assigned the same unit
% 'InitSlice', 1xN-2 set the slice that is shown when the
% figure is opened.
% 'InitRot', int initial rotation angle of the displayed
% image
% 'InitPoint', 1x2 coordinates along the first 2
% dimensions of img, where the marker is
% placed
% 'DimLabel', cell{char} char arrays to label the individual
% dimensions in the input data. Cell
% entries can be empty to use default
% label.
% 'DimVal', cell{cell{char}} char arrays containing the axis-values
% or cell{int} for each dimension. Cell entries can be
% empty to use default enumeration. Vals
% must not be char, but is encouraged.
% 'Permute' 1xN permutation vector, that works similar
% to matlabs permute function. It is used
% to access image information in
% different order. Use this when working
% with large image matrices, to avoid
% additional memory usage from calling
% permute.
% 'fps', double defines how many times per second the
% slider value provided by 'LoopDim' is
% increased.
% 'LoopDim', int Dimension, along which the slider is
% incremented 'fps' times per second
% 'ROI_Signal', Nx2 vertices polygon that defines a ROI in
% the initial slice.
% 'ROI_Noise', Nx2 vertices polygon that defines a ROI in
% the initial slice.
% 'SaveImage', filename When provided, the image data is
% prepared according to the other inputs,
% but no figure is shown. The prepared
% image data is directly saved to file
% under filename.
% 'SaveVideo', filename When provided, the image data is
% prepared according to the other inputs,
% but no figure is shown. 'fps' gives the
% framerate for the video that is saved
% under filename. Only '.avi' and '.gif'
% supported so far. 'LoopDim' can be used
% to specify the dimension along which
% the video loops.
