This paper presents a new error equalisation method for construction of mosaics built from a large number of images that may not completely cover a scene (’sparse’ coverage without all the overlapping images in the neighbourhood). The proposed method is shown to achieve consistent sparse image mosaic construction with the final alignment error no bigger, and in most cases smaller, than the erro...

In totally endoscopic coronary artery bypass surgery, intra-operative assessment of anastomotic quality is needed. We evaluated the endoscopic application of epicardial ultrasound to visualize the coronary anastomosis and detect a construction error. In 8 pigs (71-78kg), 16 internal mammary artery to left anterior descending coronary artery anastomoses were constructed conventionally, either co...

25% of the total revenue earning is achieved from Textile exports for some countries like Bangladesh. It is thus important to produce defect free high quality garment products. Inspection processes done on fabric industries are mostly manual hence time consuming. To reduce error on identifying fabric defects requires automotive and accurate inspection process. Considering this lacking, this res...

The connecting rod is a critical part inside the marine engine. The inspection of its important parameters is directly related to the assembly and quality of the marine engine. A coordinate measuring machine (CMM) is a conventional choice to measure the parameters of a connecting rod. However, CMM requires significant resources in time and cost, which leads researchers into in-situ measurement....

State-of-the-art infrastructure management systems utilize Markov Decision Processes as a methodology for maintenance and rehabilitation (M&R) decision-making. The underlying assumption in this methodology is that an inspection is performed at the beginning of every year, and that inspections reveal the true condition state of the facility, with no error. As a result, after an inspection, the d...

the paper presents an economical model for double variable acceptance sampling with inspection errors. taguchi cost function is used as acceptance cost while quality specification functions are normal with known variance. an optimization model is developed for double variables acceptance sampling scheme at the presence of inspection errors with either constant or monotone value functions. the m...

Research and development related to human factors in aviation has traditionally focused on the pilot and the cockpit. However, recent reports have attributed 18% of all accidents to maintenance factors. The aircraft inspection/maintenance system is a complex one with many interrelated human and machine components. The linchpin of the system is however, the human. Since it is difficult to elimin...

nowadays cmm machines are widely used in surface measurement and inspection. as inspection results from cmm machine are obtained by the means of measuring surfaces with direct contact, they are more precise than non-contact method (like optical measurement). however, cmm machines give more reliable and accurate results rather than non-contact methods but also these results come with error when ...

We present a novel online inspection method for manufacturing processes that automatically adapts to variations in part and environmental properties. This method is based on a developmental learning architecture comprising a procedure that focuses attention to apparently defective regions, a recognition method that performs automatic feature derivation based on a set of training images and hier...

In this paper, we present a new technique for estimating an arbitrary skew angle using a simple and efficient text row accumulation based on the statistics of the 1st and 2nd orders. In contrast to other works, where an image resolution of 100-300 dpi is necessary, a lower resolution (50 dpi) is enough for our method to obtain a correct result. The performance of the method was evaluated on the...
