Applies the Hough transform to an image. For every input band, outputs a band where lines are detected by thresholding the Hough transform with a value of lineThreshold. The output band is named [input]_lines, where [input] is the name of the original band. The defaults provided for the parameters are intended as a starting point for use with UINT8 images.
| Usage | Returns |
|---|---|
ee.Algorithms.HoughTransform(image, gridSize, inputThreshold, lineThreshold, smooth) | Image |
| Argument | Type | Details |
|---|---|---|
image | Image | The image to which to apply the transform. |
gridSize | Integer, default: 256 | Grid size. |
inputThreshold | Float, default: 64 | Value threshold for input image. Pixels equal to or above this value are considered active. |
lineThreshold | Float, default: 72 | Threshold for line detection. Values equal to or above this threshold on the Hough transform are considered to be detected lines. |
smooth | Boolean, default: true | Whether to smooth the Hough transform before line detection. |
