For realizing Shipboard Infrared Surveillance System detects the dim point targets under background of sea and sky,this paper presents a new method which combines multi-morphology filter with gradient detection and applies to infrared images filter and targets detection.

To detect weak point target under the background of sky and sea by shipboard infrared surveillance system,the detection algorithm of far and dim target was mainly studied based on the constitution of the target recognition system and target information processing flow of detection and recognition.
