The VisionX image formats allow for multiple channels, 3D images, image
sequences and many pixel types. The Image Utilities for these images
may be grouped into three primary functions. 1. Data format conversion
to and from external image file formats, 2. Data extraction to select
a subset of the image data and data construction to reformulate the
image data structure.
| Command | Function: Format Conversion |
|---|
| vformat | - (vx) change image format to VisionX format
actual formats supported are platform dependent |
| vrawtovx | - Convert a raw image to VisionX format
useful for many non-standard image formats,
if the image has a header use dd to skip over it |
| vxto | - change image format from VisionX format
the formats supported are platform dependent |
| vxtotiff | - generate tiff format image set for VisionX image sequences |
| vxtopnm | - convert files from VisionX to pnm format
all visionx programs can output pnm files by using a ",p" file extension
vxtopnm in addition supports the ascii version of the pnm formats |
| vxctops | - convert VisionX image files to Postscript
backup (old) version, use if "vxto -ps" (requires netpbm) is not available |
| vxtoraw | - write out the raw image data from a file |
| Command | Function: Complex Image Construction |
|---|
| vcp | - make a copy of a VisionX file |
| vcat | - concatenate a set of VisionX files (for construction of 3D images and image sequences) |
| vxfile | - Append a VisionX file to the end of a VisionX file
(like vcat but appends to an existing file) |
| vdim | - convert between different multidimensional formats |
| vtile | - paste an image sequence into a single image (useful for presentations of 3D images and image sequences) |
| vclip | (vclipx) - clip
a region of a VisionX file allows almost any consecutive subregion
to be selected
except channels which can be extracted by vchan below
vclipx allows the use of aonther clipped image as the clipping template |
| v3roi | - select a 3D region of interest(ROI).
This is a more user convenient form of vclip specifically for ROI selection |
| vchan | manipulate multi-channel images
permits a single to channel to be extracted and for channels to be combined
also includes some complex number transformations |
| vflip | - flip or transpose an image about an axis |
| vfix | - change the image format (pixel type) of a VisionX image file |
| vifx | - Scale image data and convert to byte or float format |
| v3pad | - perform three-dimensional zero-padding |
| Command | Function: Image Modification |
|---|
| vmag | - magnifies, changes the size of a VisionX image |
| vpix | - primitive operations on the pixels of a VisionX image |
| vmath | - compute a primitive mathematical function of the pixels of a VisionX image |
| vembed [vop] | - perform an operation between two images or image sequences |
| vop | - perform an operation between two images or image sequences |
| v3rbody | - Three-dimensional Rigid-Body Transformation |
| v3mip | - performs interpolation, transformation to different views and projections of input 3D image |
