• [x] Added a button Open.. to let user browse which image they want to open in the main GUI window
• [x] Added a new fragment class ImportImage so a window will pop up when Open.. is clicked
• [x] The new window has a textfield to allow user input file path directly or by selecting files from clicking browse.. button on the right, then press OK button to commit
• [x] The file selector popped up from browse.. button now supports *.png, *.bmp, *.jpeg and *.jpg file extension (can be extended later)
• [x] Added try.. except.. block to handle exceptions if file path is invalid or image failed to open

• [x] Forced button width in basic actions (Inverse Color, Greyscale, Flip Horizontal, Flip Vertical), these buttons have long labels so the window could abbreviate them when load up (Invers..., etc.), if other tabs are clicked, the labels will show up all and the middle border will move to the right, causing image moving to the right as well. Now fixed.
• [x] Add slider value as integer to the right hand side of the slider itself, showing corresponding value clearly to users.
• [x] Use spinner instead of label so user can also adjust the slider by input values in the spinner

Major Project Refactor

Moved ALL functionalities/features to EngineModel which performs all logical operations for the image engine. Controllers from now on should only handle Events and then call appropriate methods in the model.

Note that there can be more than 1 model and more than 1 controller as long as their functions do not overlap (see PAC or HMVC patterns).

WIP

• [x] Tony's pipeline migration
• [x] Steven's branch

• [x] override toString for transformations so that display names in “Transformations” are meaningful
• [x] Full history support
  • [x] ability to click a step in “Transformations” and go back to that state
  • [x] Undo now does not clear history
  • [x] Add ability to redo a previous step

• [x] Added a top bar in image panel to toggle between sliders and parallel view.
• [x] The image views in parallel view can adjust their widths based on width of the image panel.
• [x] Fixed alignment of the horizontal slider to make it look nicer.
• [x] Removed export parallel view.

Methods

• [x] Point (Nearest Neighbour)
  • [x] PointWithZero (Filled zeros when sample is not available at that site)
• [x] Bilinear
• [x] Bicubic ~- [ ] Spline~
• [x] Lanczos ~- [ ] Jinc~
• [x] Lagrange

UI (@zhao-xuan Please help 😭)

• [x] Basic UI control in Filters tab
• [x] Scroll scaled image

NPE when user delete number in any spinner in filter tabs (like RGB)

Introduced in f3b073f83ae7436773fb25fa43ee989728d7be43 in #33 Should use doubleSpinner the factored out component rather than raw spinner

• [x] Now add a slider at the bottom of the image, it will drag a vertical line to compare between the processed image and the original one.
• [x] Fixed bug 1: Slider can now update its max value everytime new image is imported so it now works normally on every new image, before the value is locked to the initial image when program loads up.
• [x] Fixed bug 2: Slider now move back to initial state (rightmost) when new image is imported, filter, colouring applied.
• [x] Add feature in the top bar menu to allow user save their images in parallel mode. Simply click Export parallel to save in current state.

Some improvements can have in the future:

• Add a vertical slider so a region can be shown as original image, or user may want to compare vertically.
• Give a selection whether user want LHS or RHS be original image (and top or bottom, if previous one implemented).
• Add a spinner just like in filter panel so user can adjust the position of the line by value.

• Add sliders for hue, saturation and brightness
• Add 'Adjust' and 'Reset' buttons
• Centralise the sliders and make it possible for RGB factors to be greater than 1

image processing commands are now stored in linkedlist, one command in each pipeline stage. processing is finished by passing image iteratively through all pipeline stages each time select or deselect an operation result in pass source image again from start of the pipeline

Implemented visualization of CNN's each layer's output.

• [x] support importing any torch layers with output more than 2 dimentions
• [x] support export to json file

• [ ] Before making changes, post it in Jira at least (better to say in WhatsApp group as well)
• [ ] Branch out your own branch, do not work on other's branch directly. Use git rebase or cherrypick to catch up with other's branch
• [ ] Don't merge directly to master, merge to develop (in MOST cases)
• [ ] At least 3 people should review the PR before merging. After you've done your review, use the Submit review function in PR or just leave a comment below at least.

Naming Strategies

• [ ] Branch Name: <Jira-code>-<whatever-you-want-to-put>
  • Example: IP-1-image-loading
  • Note that the IP should be capitalised
