A system for a vehicle comprising a driver operable steering device and a semi-autonomous or autonomous control system, the system comprising: at least one imaging means having a field of view encompassing at least a portion of the driver operable steering device and being configured to collect, in use, a first image data set representing a raw image of a subject within said field of view; and a control module being configured to process said first image data for making a determination as to whether a driver is currently operating said driver operable steering device or not by determining whether both of the driver's hands are off the steering device or whether both of the driver's hands are not off the steering device; wherein, in response to making said determination, the system is configured to trigger a semi-autonomous or autonomous control system; and wherein the control module comprises one or more processors having at least one memory associated therewith and having at least one algorithm executable thereon configured to process the said first image data for making the determination as follow: (i) receive the first image data set ; (ii) compare the first image data set with a background image data set stored in said at least one memory; (iii) create a first modified data set in dependence upon said first image data set in dependence upon said background image data set; (iv) create a second modified data set in dependence upon a brightness characteristic associated with data elements of the first modified data set ; and (v) create a third modified data set by identifying and blending incongruous elements within the second modified data set . at least one imaging means having a field of view encompassing at least a portion of the driver operable steering device and being configured to collect, in use, a first image data set representing a raw image of a subject within said field of view; and a control module being configured to process said first image data for making a determination as to whether a driver is currently operating said driver operable steering device or not by determining whether both of the driver's hands are off the steering device or whether both of the driver's hands are not off the steering device; wherein, in response to making said determination, the system is configured to trigger a semi-autonomous or autonomous control system; and wherein the control module comprises one or more processors having at least one memory associated therewith and having at least one algorithm executable thereon configured to process the said first image data for making the determination as follow: (i) receive the first image data set ; (ii) compare the first image data set with a background image data set stored in said at least one memory; (iii) create a first modified data set in dependence upon said first image data set in dependence upon said background image data set; (iv) create a second modified data set in dependence upon a brightness characteristic associated with data elements of the first modified data set ; and (v) create a third modified data set by identifying and blending incongruous elements within the second modified data set . (i) receive the first image data set ; (ii) compare the first image data set with a background image data set stored in said at least one memory; (iii) create a first modified data set in dependence upon said first image data set in dependence upon said background image data set; (iv) create a second modified data set in dependence upon a brightness characteristic associated with data elements of the first modified data set ; and (v) create a third modified data set by identifying and blending incongruous elements within the second modified data set . <EOS>
