noixle

Disclaimer: This is a project I did for university. For serious image processing prototyping/exploration I would recommend python with napari, opencv and/or skimage and the other well documented image processing libraries :)

Here comes:

Imageprocessing with commandline-flavor.

Build on Qt and OpenCV with c++17ish

build on linux

1. clone the project
2. cd inside the directory
3. make a new directory called build
4. run cmake . -B ./build
5. cd into build
6. run make
7. run the program with ./noixle

build on windows

Generate buildfiles for visual studio with cmake

usage

• help | shows this message

• echo | displays a message to the user

• open [file_path (optional)] | opens an image

• save [file_path (optional)] | saves the currently opened image

• exit | exits the programm

• revert | reverts back to last state

• clear | clear everything

• toggle_perf_measurement | toggles the performance measurement

• history | shows the command history

• record [start | stop] | starts or stops the command recording

• load_macro | loads and plays a recorded macro

• snapshot | saves the image as snapshot and displays it in a new tab-window

• load_snapshot [snapshot_index] | loads the selected snapshot or by provided snapshot index

• iminvert | inverts the currently opened image

• imfilter ['median' | 'gaussian' | 'bilateral' | 'sobel' | 'dilate' | 'erode' | 'laplace'] | applies filter kernel to current image. no argument is custom Kernel

• imcconvert [gray | color] | converts the active image to the specified mode

• histogram ['cumulative'] | displays a histogram of the currently viewed image

• imequalize | improves the image contrast by equalizing the histogram

• imgammacorrect [gamma_value]| corrects the gamme by the specified value

• imrotate [angle in deg] | rotates the active image by the given angle to the left

• impixelize [pixelsize] | pixelizes the active image

• imshadingcorrect | corrects the shading on an image

• imintegral | calcuates the integralimage of the active image

• imresize [width, heigh] | resize image to give arguments

• sub [a b] | subtract b from a, image or scalar, i is active image, s marks snaphot images Example: sub s1 s2

• add [a b] | add b to a, image or scalar, i is active image, s marks snaphot images Example: add i 25

• mul [a b] | multiply a with b, image or scalar, i is active image, s marks snaphot images Example: mul s1 2

• div [a b] | divide a by b, image or scalar, i is active image, s marks snaphot images Example: div s2 s1

• imdft | shows the spectral domain of the image

• immerge [channel1 channel2 channel3] | merge channels, i is active image, s marks snaphot images Example: merge s0 s3

• gol | Do one iteration of conway's game of life, each pixel is a cell (Image has to be binarised)

• Use Tab to autocomplete!

• You can zoom with scrolling in and out while pressing Ctrl/Cmd or by using the + and - keys

• You can move the view while being zoomed in by pressing Ctrl/Cmd + Alt/Option and dragging the mouse
