Image processing system, image processing method, and program storage medium

Abstract

Provided is an image processing system, an image processing method, and a program for preferably detecting a mobile object. The image processing system includes: an image input unit for receiving an input for some image frames having different times in a plurality of image frames constituting a picture, which is of a pixel on which the mobile object appears or a pixel on which the mobile object does not appear, for selected arbitrary one or more pixels in an image frame at the time of processing; and a mobile object detection model constructing unit for learning a parameter for detecting the mobile object based on the input.

1 . An image processing system comprising:
 at least one memory storing instructions; and   at least one processor configured to process the instructions to control the image processing system to:
 receive an input to place, on each of a plurality of captured images, a first object indicating at least one pixel of a vehicle region and a second object indicating at least one pixel of a region which is different from the vehicle region; and 
 generate, based on the plurality of the first objects and the plurality of the second objects placed on the plurality of captured images, a learning data indicating the vehicle region, the learning data being capable to be learned by a detector that detects at least one vehicle. 
   
     
     
         2 . The image processing system according to  claim 1 , wherein
 the at least one processor is configured to process the instructions to control the image processing system to:
 accept a first input operation to specify the vehicle region by placing the first icon in the vehicle region. 
   
     
     
         3 . The image processing system according to  claim 2 , wherein
 the second icon is different to the first icon.   
     
     
         4 . The image processing system according to  claim 3 , wherein
 the at least one processor is configured to process the instructions to control the image processing system to:
 accept a second input operation to specify whether one or more pixels selected from any image frame is located on a background region or the vehicle region. 
   
     
     
         5 . The image processing system according to  claim 1 , wherein
 the at least one processor is configured to process the instructions to control the image processing system to:
 a first input operation to specify the vehicle region by placing a plurality of the first icon in the vehicle region. 
   
     
     
         6 . The image processing system according to  claim 1 , wherein
 the at least one processor is configured to process the instructions to control the image processing system to:
 calculating differences between a first background model generated based on an image frame at the time of processing, a second background model in which an influence of an image frame at the time of processing is smaller than that of the first background model, and a third background model in which an influence of an image frame at the time of processing is smaller than that of the second background model, and 
 learning a parameter for detecting the at least one vehicle using the first background model, the second background model, and the third background model, based on the input. 
   
     
     
         7 . An image processing method performed by at least one computer, the method comprising: receiving an input to place, on each of a plurality of captured images, a first object indicating at least one pixel of a vehicle region and a second object indicating at least one pixel of a region which is different from the vehicle region; and
 generating, based on the plurality of the first objects and the plurality of the second objects placed on the plurality of captured images, a learning data indicating the vehicle region, the learning data being capable to be learned by a detector that detects at least one vehicle.   
     
     
         8 . A non-transitory computer readable recording medium storing program instructions for causing a computer to perform:
 receiving an input to place, on each of a plurality of captured images, a first object indicating at least one pixel of a vehicle region and a second object indicating at least one pixel of a region which is different from the vehicle region; and   generating, based on the plurality of the first objects and the plurality of the second objects placed on the plurality of captured images, a learning data indicating the vehicle region, the learning data being capable to be learned by a detector that detects at least one vehicle.
