frame_list_input¶
You can find the available option for the image_reader here
Reads a list of image file names and generates stream of images and associated<br>time stamps
Configuration¶
Variable | Default | Tunable | Description |
---|---|---|---|
frame_time | 0.03333333 | NO | Inter frame time in seconds. The generated timestamps will have the specified<br>number of seconds in the generated timestamps for sequential frames. This can be<br>used to simulate a frame rate in a video stream application. |
image_list_file | (no default value) | NO | Name of file that contains list of image file names. Each line in the file<br>specifies the name of a single image file. |
image_reader | (no default value) | NO | Algorithm configuration subblock |
path | (no default value) | NO | Path to search for image file. The format is the same as the standard path<br>specification, a set of directories separated by a colon (‘:’) |
Input Ports¶
There are no input ports for this process.
Output Ports¶
Port name | Data Type | Flags | Description |
---|---|---|---|
image | kwiver:image | (none) | Single frame image. |
image_file_name | kwiver:image_file_name | (none) | Name of an image file. The file name may contain leading path components. |
timestamp | kwiver:timestamp | (none) | Timestamp for input image. |
Pipefile Usage¶
The following sections describe the blocks needed ot use this process in a pipe file.
Pipefile block¶
# ================================================================
process <this-name>
:: frame_list_input
# Inter frame time in seconds. The generated timestamps will have the specified
# number of seconds in the generated timestamps for sequential frames. This can
# be used to simulate a frame rate in a video stream application.
frame_time = 0.03333333
# Name of file that contains list of image file names. Each line in the file
# specifies the name of a single image file.
image_list_file = <value>
# Algorithm configuration subblock
image_reader = <value>
# Path to search for image file. The format is the same as the standard path
# specification, a set of directories separated by a colon (':')
path = <value>
