Intersection of the region should be always 1px smaller on both axies

• New ridge detection
• new preparation

• ridge detection auto threshold

• preparation auto threshould adjustment

• Halcon bug workaround

During finding complementary region, halcon sometimes recognizes image size incorrectly. Added additional intersection to ensure that complementary region has correct size.

• improved corner detection

• new ridge detection

• new ridge detection

• Rescale parameters(sys_v_scale and sys_h_scale) added for rescaling the image during preparation
• scaleV parameter removed

parameters file 'parameters.json' should be placed under 'Documents\LaserVision\Recepies\G09E_gelpack'

content of the file should be

{  
"sys_v_scale": 0.998,
  "sys_h_scale": 0.986
}
