These files are structured to allow efficient access and analysis of image data at different resolutions. Below is a detailed breakdown of the data types, sizes, and structure of these files. + +### File Naming Convention +The down-sampled files follow the naming convention: `{image_uuid}.{colorspace}.pyr_{level}.jpeg + +- `{image_uuid}`: Unique identifier for the image. +- `{colorspace}`: Color space used (e.g., `lab`, `rgb`, `hsv`). +- `{level}`: Down-sampling level (e.g., `1`, `2`, etc.). + +### Data Structure +Each `lab.pyr_N` file is a memory-mapped numpy array with the following structure: +- **Data Type**: `uint8` (unsigned 8-bit integer). +- **Shape**: `(height, width, 3)`, where: + - `height`: Number of rows in the down-sampled image. + - `width`: Number of columns in the down-sampled image. + - `3`: Number of color channels (e.g., L, a, b for LAB color space). + +### Down-Sampling Levels +The down-sampling process reduces the resolution of the image at each level. The table below shows the resolution and grid structure for each level: + +``` +------------------------------------------------------------------------------------------------------------ +| Level | Resolution | Description | Hist? | Tiled Hist | Point-Spread | Label +| | (w × h) | | | (16X3) | (1X3 or 9X3) | +|-------|-------------|---------------------------------|-------|------------|--------------|--------------- +| 0 | 1280 × 960 | Original resolution | No | No | No | orig +| 1 | 640 × 480 | Down-sampled by a factor of 2 | Yes | No | No | blur +| 2 | 320 × 240 | Down-sampled by a factor of 4 | Yes | No | No | blur++ +| 3 | 160 × 120 | Down-sampled by a factor of 8 | Yes | 81 | No | smhist +| 4 | 80 × 60 | Down-sampled by a factor of 16 | Yes | 25 | No | medhist +| 5 | 40 × 30 | Down-sampled by a factor of 32 | Yes | 9 | No | lghist +| 6 | 20 × 15 | Down-sampled by a factor of 64 | Yes | No | 9 | smblk +| 7 | 10 × 8 | Down-sampled by a factor of 128 | Yes | No | 5 | medblk +| 8 | 5 × 4 | Down-sampled by a factor of 256 | Yes | No | 1 | lgblk +``` + +## License + +This project is licensed under the MIT License.

Design the Test Function +### Test Scope +Unit tests to verify the functionality of the `ColorFeaturesPyramid` class. + +### Test Cases +1. **Initialization Test**: + - Verify that the class initializes correctly with default and custom parameters. + - Ensure that the `check_params` function from `utils.py` is used correctly. +2. **Down-Sampling Test**: + - Verify that the down-sampling process works as expected. + - Check that the down-sampled images are saved correctly. +3. **Tile Analysis Test**: + - Verify that the tile analysis produces the expected output. + - Ensure that the histograms are computed correctly. +4. **Edge Cases**: + - Test with invalid inputs (e.g., non-existent image, invalid color space). + - Test with extreme values for parameters (e.g., very large or small tile sizes). + +### Testing Framework +Use `pytest` for writing and running the tests. + +## 3. Document the Test Function +- Write clear docstrings for the test function. +- Include examples of how to use the `ColorFeaturesPyramid` class. +- Document the expected behavior and assumptions. +- Add comments to explain the purpose of each test case. + +## 4.
