| 4-neighbors | Returns four values, each value is either a list containing the coordinates of a 4-neighbor of (i,j) in matrix or nil if the neighbor would be outside of the matrix. The order of the values is top, left, bottom, right. |
|---|---|
| 8-neighbors | Returns eight values, each value is either a list containing the coordinates of an 8-neighbor of (i,j) in matrix or nil if the neighbor would be outside of the matrix. The order of the values is top, left, bottom, right. |
| bit-matrix->ub8-image | |
| component-boundary | Returns the union of the interal and external boundaries of the component whose value is label. neighbor-function is 4-neighbors by default, using 8-neighbors will use 8 neighbors instead of 4 for computing the boundary. |
| component-external-boundary | Returns the external boundary of component label in the labelled connected components matrix. neighbor-function is 4-neighbors by default, using 8-neighbors will use 8 neighbors instead of 4 for computing the boundary. |
| component-internal-boundary | Returns the internal boundary of component label in the labelled connected components matrix. neighbor-function is 4-neighbors by default, using 8-neighbors will use 8 neighbors instead of 4 for computing the boundary. |
| discrete-convolve-image | |
| distance-transform | Computes the distance transform of an image. The distance transform is a matrix where the value of each pixel is the distance between that pixel and the closest zero-valued pixel. This function uses the algorithm described in Soille, 2003, p. 48. |

| jpeg-gray-to-gray-image | |
| jpeg-rgb-to-argb-image | |
| jpeg-rgb-to-gray-image | |
| label-components | Returns a new matrix containing labels of the connected components of matrix. The default neighbor-fucntion is 4-neighbors. |

| read-image-file | |
| read-jpeg-file | |
| read-tiff-file | reads a TIFF file and returns either a 32-bit ARGB image or an 8-bit grayscale image |
| resize-image | Resize an image to new size y rows by x columns. If constrain proportions is t, then the xscale and yscale will be set to whichever scale has the largest absolute value and the image will be padded as needed. |
