IMAGE PRE­PROCESSING Clause Samples

The 'Image preprocessing' clause defines the procedures and requirements for preparing images before they are used in a particular process or system. This typically involves steps such as resizing, normalization, noise reduction, or format conversion to ensure that images meet specific technical standards or are compatible with downstream applications. By standardizing how images are handled prior to use, this clause helps ensure consistency, improves the quality of results, and reduces errors caused by incompatible or poor-quality image data.
IMAGE PRE­PROCESSING. Pre­processing plays a large role in determining the classification results obtained within this project when using appearance based techniques for representing or matching images. This is mainly due to the outdoor, far field nature of the AVITRACK project (which adds large amounts of perspective distortion and lighting variations), as well as the low contrast pictures obtained from the cameras used. Image pre­ processing allows the effects of perspective distortion to be minimised using scaling algorithms, as well as limiting the effects of lighting variations. Pre­processing has a computational cost attached to it; however, if a suitable balance can be found between cost and benefits, final recognition rates can be improved without unduly reducing the overall speed. In this project, different rescaling techniques were trialled, with differing computational costs associated with them, from the very low (nearest neighbour interpolation), to the highest (bi­cubic interpolation). Although the cost per use for each interpolation method is quite low overall (as compared to, for example, locating scale invariants), the images within a matching system often requires multiple rescaling before a classification may be decided upon. This therefore increases the time required by a factor equal to the number of images to resize, and which grows with increased image size. Within this project, it was found experimentally (See [85]), that little difference was evident between bi­linear and bi­cubic rescaling methods, both in visual examination and classification rates. It was therefore decided that the extra smoothing available within the bi­cubic scheme was superfluous to requirements and that to maximise efficiency and classification rates, bi­linear interpolation may safely be used. Having completed work using Gaussian scale space, it is possible that an alternative to using bi­linear or bi­ cubic scaling would have been to use nearest neighbour interpolation then smoothed the image using a Gaussian convolution. This idea is normally referred to as a Gaussian pyramid. The drawbacks to using this type of technique are that it is most efficient when the desired size is a power of two from the original image. This is unlikely to occur within the AVITRACK image files, as the images are often non­square and are of arbitrary size. It should also be noted that the blurring achieved by the Gaussians within a Gaussian pyramid is recreated using pixel averages within the bi­lin...

  • Subprocessing The data importer shall not subcontract any of its processing operations performed on behalf of the data exporter under the Clauses without the prior written consent of the data exporter. Where the data importer subcontracts its obligations under the Clauses, with the consent of the data exporter, it shall do so only by way of a written agreement with the subprocessor which imposes the same obligations on the subprocessor as are imposed on the data importer under the Clauses. Where the subprocessor fails to fulfil its data protection obligations under such written agreement the data importer shall remain fully liable to the data exporter for the performance of the subprocessor's obligations under such agreement.

  • Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at a P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.

  • STATEWIDE CONTRACT MANAGEMENT SYSTEM If the maximum amount payable to Contractor under this Contract is $100,000 or greater, either on the Effective Date or at any time thereafter, this section shall apply. Contractor agrees to be governed by and comply with the provisions of §§▇▇-▇▇▇-▇▇▇, ▇▇-▇▇▇-▇▇▇, ▇▇-▇▇▇-▇▇▇, and ▇▇- ▇▇▇-▇▇▇, C.R.S. regarding the monitoring of vendor performance and the reporting of contract information in the State’s contract management system (“Contract Management System” or “CMS”).

  • ELECTRONIC WORKFLOW SYSTEM OGS reserves the right to incorporate an electronic workflow system that may include elements of the Authorized User RFQ process. OGS reserves the right to post Authorized User Contract usage of Centralized Contracts. For Lot 4 only, when provided for in the RFQ and resultant Authorized User Agreement, the Authorized Users may reimburse travel expenses. All rules and regulations associated with this travel can be found at ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇.▇▇/agencies/travel/travel.htm. In no case will any travel reimbursement be charged that exceeds these rates. All travel will be paid only as specified within the Authorized User Agreement and must be billed with the associated services on the same Invoice with receipts attached. The Contractor shall receive prior approval from the Authorized User for any travel that occurs during the term of an Authorized User Agreement. Parking fees and/or parking tickets shall not be paid by an Authorized User. Unless otherwise specified in writing by the Authorized User, a vehicle will not be provided by Authorized User to the Contractor for travel. Therefore, the Contractor will be responsible for ensuring that the Contractor has access to an appropriate vehicle (e.g., personal vehicle or rental vehicle) or common carrier with which to carry out any necessary travel. For the Contractor to obtain reimbursement for the use of a rental vehicle, such use must be justified as the most cost- effective mode of transportation under the circumstances (including consideration of the most effective use of time). The Contractor is responsible for keeping adequate records to substantiate any claims for travel reimbursement. All services provided under the resultant Authorized User Agreement must be performed within CONUS. There are no BONDS for this Contract. However, an Authorized User may require in an RFQ a performance, payment or Bid bond, or negotiable irrevocable letter of credit or other form of security for the faithful performance for the resultant Authorized User Agreement. Pursuant to New York State Executive Law Article 15-A and Parts 140-145 of Title 5 of the New York Codes, Rules and Regulations (“NYCRR”), the New York State Office of General Services (“OGS”) is required to promote opportunities for the maximum feasible participation of New York State-certified Minority- and Women-owned Business Enterprises (“MWBEs”) and the employment of minority group members and women in the performance of OGS contracts.
