Gives information on the quality of image registration between two (theoretically) co-registered images. The input is two images with the same number of bands.

The fourth band is the value of the correlation coefficient for that pixel [-1 : +1].

Performs G-Means clustering on the input image. Iteratively applies k-means followed by a normality test to automatically determine the number of clusters to use.

Any cluster that spans a cell or tile boundary may receive two different labels in the two halves. Any input pixels with partial masks are fully masked in the output. This algorithm is only expected to perform well for images with a narrow dynamic range (i.e. bytes or shorts).

The default arguments select approximately one year's worth of good data.

Note that in rare circumstances, when the tile boundary aligns with a Landsat WRS cell bounadry, queries for adjacent tiles may yield conflicting results. This is why it is important that this algorithm only be used with statistical methods that can tolerate these inconsistencies.

## ee.Algorithms.TemporalSegmentation.Ewmacd

Exponentially Weighted Moving Average Change Detection. This algorithm computes a harmonic model for the 'training' portion of the input data and subtracts that from the original results.

Disturbed pixels are indicated when the charts signal a deviation from the given control limits.

The output is a 5 band image containining the bands:

ewma: a 1D array of the EWMA score for each input image. Negative values represent disturbance and positive values represent recovery.

harmonicCoefficients: A 1-D array of the computed harmonic coefficient pairs. The coefficients are ordered as [constant, sin0, cos0, sin1, cos1...]

rmse: the RMSE from the harmonic regression.

rSquared: r-squared value from the harmonic regression.

## ee.Algorithms.TemporalSegmentation.LandTrendr

Landsat-based detection of Trends in Disturbance and Recovery: temporally segments a time-series of images by extracting the spectral trajectories of change over time. The first band of each image is used to find breakpoints, and those breakpoints are used to perform fitting on all subsequent bands. The breakpoints are returned as a 2-D matrix of 4 rows and as many columns as images. The first two rows are the original X and Y values. The third row contains the Y values fitted to the estimated segments, and the 4th row contains a 1 if the corresponding point was used as a segment vertex or 0 if not. Any additional fitted bands are appended as rows in the output. Breakpoint fitting assumes that increasing values represent disturbance and decreasing values represent recovery.

## ee.Algorithms.TemporalSegmentation.Verdet

Vegetation Regeneration and Disturbance Estimates through Time, forest change detection algorithm. This algorithm generates a yearly clear-sky composite from satellite imagery, calculates a spectral vegetation index for each pixel in that composite, spatially segments the vegetation index image into patches, temporally divides the time series into differently sloped segments, and then labels those segments as disturbed, stable, or regenerating. Segmentation at both the spatial and temporal steps are performed using total variation regularization.

The output consists of a 1D array per pixel containing the slope of fitted trend lines. Negative values indicate disturbance and positive values regeneration.

---|---|

`Image.reduce(reducer)` | Image |

Argument | Type | Details |
---|---|---|

this: `image` | Image | The image to reduce. |

`reducer` | Reducer | The reducer to apply to the given image. |

## ee.Image.reduceConnectedComponents

Applies a reducer to all of the pixels inside of each 'object'. Pixels are considered to belong to an object if they are connected (8-way) and have the same value in the 'label' band. The label band is only used to identify the connectedness; the rest are provided as inputs to the reducer.

Usage | Returns |
---|---|

`Image.reduceConnectedComponents(reducer, ` | Image |

Argument | Type | Details |
---|---|---|

this: `image` | Image | The input image. |

The reducer output names determine the names of the output bands: reducers with multiple inputs will use the output names directly, while reducers with a single input will prefix the output name with the input band name (e.g. '10_mean', '20_mean', etc.).

Reducers with weighted inputs can have the input weight based on the input mask, the kernel value, or the smaller of those two.

It requires a homogeneous kernel, a single-input reducer and either MASK, KERNEL or no weighting. The 'window' method uses a running window, and has the same requirements as 'boxcar', but can use any single input reducer. Both methods require considerable additional memory. |

The reducer output names determine the names of the output bands: reducers with multiple inputs will use the output names directly, reducers with a single input and single output will preserve the input band names, and reducers with a single input and multiple outputs will prefix the output name with the input band name (e.g. '10_mean', '10_stdDev', '20_mean', '20_stdDev', etc.).

Registers an image to a reference image while allowing local, rubber sheet deformations.

## ee.Image.resample

An algorithm that returns an image identical to its argument, but which uses bilinear or bicubic interpolation (rather than the default nearest-neighbor) to compute pixels in projections other than its native projection or other levels of the same image pyramid.
