Photomosaic Maker v5.3

Fixes

Fixed #28

Notes

Since ubuntu 18.04 and macos 10.15 supports are dropped by github actions, we will no longer ship binaries for these versions.

Photomosaic Maker v5.2

New features

• Add support for tile info export when transparency masking or saliency is enabled

Changes

• Add progress info when assembling sorted tiles on grid
• --video mode will no longer export a MP4 video. Instead, individual frames will be exported as images.
• Internal temporary image will be stored in memory in uint8 format instead of float32, which should reduce memory footprint significantly.

Fixes

• Improve error catching for imread

Photomosaic Maker v5.1

New Features

1. Added a type of resize method call fit (--resize_opt=fit). This method keeps the aspect ratio of the tiles and add white padding to achieve the target aspect ratio (either user-defined through explicit tile-size or inferred)

Fixes

1. Fixed GPU acceleration not enabled in gui.py (note: GPU acceleration is not available in prebuilt binary)
2. Fixed the problem that appears when infer size is not used.

Photomosaic Maker v5.0

New Features

1. Added option transparency masking (--transparent flag for CLI) so tiles won't be placed on the transparent region of the destination image

Changes

1. Added macos 12 and ubuntu 20.0 build (not tested)
2. For the salient option, the background color option is removed. Now the background will be transparent for better flexibility and room for further editing.

Photomosaic Maker v4.2

Version 4.2 Changes

• Add support for dithering

Photomosaic Maker v4.1

Version 4.1 Changes

Add tile info export (#12).

Fix a integer overflow problem

Photomosaic Maker v4.0

Version 4.0 changes:

This major version includes a refactored codebase to support the following new features:

1. non square tile size
2. photomosaic videos
3. better performance and GPU acceleration

v3.4-macos11

add macos 11 build

Photomosaic Maker v3.4

Version 3.4 Changes

1. Updated dependencies and now build with Python 3.9
2. Fixed #11

---

Version 3.3 Changes

1. Fix a bug of fair tile with saliency
2. Support displaying LAP (linear sum assignment, the algorithm used in fair tile mode) progress on windows

---

Version 3.2 Changes

1. Drop dependencies on scikit-learn and scipy
2. Drop ctype option
3. Fix a bug of fair tile with saliency

---

Version 3.1 Changes

1. Executable sizes on MacOS and Linux decreased significantly
2. Add CLI options for color blending

---

Version 3.0 Changes

This release brings photomosaics with improved quality due to a redesign in algorithms. The codebase is also refactored.

Note that the ubuntu build only supports ubuntu 18.04 and onwards. The binary files may take a while to open.

New features:

1. Color blending
2. Hyperparameter for balancing tile fairness and quality for unfair mode.
