20100321710SYSTEM AND METHOD FOR COLOR SPACE CONVERSION OF COLOR SPACE VALUES WHICH LIE OUTSIDE OF A TRADITIONAL COLOR SPACE BOUNDARY - The subject application is directed to a system and method for color space conversion. Image data is received comprised of a plurality of pixels having a value encoded in a first multidimensional color space. Each of the pixels encoded in the first color space is converted to a corresponding pixel encoded in a second multidimensional color space, the conversion further including transforming each of the pixels based upon a function of the pixel values in the first color space having component values defining a fractional relationship having a numerator portion and a denominator portion, with each portion including at least one of the component values. A value of each denominator portion is converted relative to a threshold value and the pixels encoded in the first color space are converted to the second color space with an alternative quantity selectively substituted for each denominator portion in accordance with the comparison.12-23-2010

20090290172SYSTEM AND METHOD FOR SCULPTED GAMUT COLOR CONVERSION - The subject application is directed to a system and method for sculpted gamut color conversion. First gamut data is received related to a first color gamut defined by a primary color space having no black component. Second gamut data is then received related to a second color gamut defined by a primary color space inclusive of a black component. At least one first color value of the first color gamut is then mapped to a second color value of a portion of the second color gamut disposed outside of the first gamut. At least one fractional black component value is then selected for each mapped color value. Non-black color data associated with each selected fractional black component is then identified. A sculpted gamut is then generated in accordance with each selected fractional black component and associated non-black color data. A color image is thereafter generated corresponding to received image data in accordance with the generated sculpted gamut.11-26-2009
20100254597System and method for facial tone indexing - The subject application is directed to a system and method for facial tone indexing. Image data comprised of a plurality of pixels encoded in at least a three dimensional component space is received and at least one candidate facial region is isolated in the received image data. The received image data is translated into a Lightness, Chroma, and Hue color space. Histogram data corresponding to the Hue of pixels is calculated in the at least one candidate facial region by discarding the low-chroma pixels first. The Hue index on which the Hue histogram peaks is identified as the Facial Tone Index. The Facial Tone Index indicates where the Hue concentration is and therefore is a single number representing the flesh tone of a face.10-07-2010

20090214108SYSTEM AND METHOD FOR ISOLATING NEAR ACHROMATIC PIXELS OF A DIGITAL IMAGE - The subject application is directed to a system and method for isolating near achromatic pixels of a digital image. First, image data encoded as a plurality of pixels is received, with each pixel having component values in a multi-dimensional color space. From the received image data, chroma data is extracted. Histogram data is then calculated from the extracted chroma data. An adapted threshold value is then determined based upon the calculated histogram data. Component values of the plurality of pixels are then compared to the determined adapted threshold value. Isolation of pixels as near achromatic then occurs in accordance with the output of the comparison of the adapted threshold value to the component values.08-27-2009
20090220120SYSTEM AND METHOD FOR ARTISTIC SCENE IMAGE DETECTION - The subject application is directed to a system and method for artistic scene image detection. First, image data is received that is encoded in a multi-dimensional color space. From the received image data, histogram data is then calculated. Dominant spike regions in the calculated histogram data are then identified. An N-sum value is then calculated from the identified dominant spike regions in the calculated histogram data. Testing of the calculated N-sum value against a predetermined threshold value then occurs. The received image data is thereafter classified as an artistic scene, a tinted artistic scene, or a sepia tone range artistic scene according to the testing results.09-03-2009

20090012511SURGICAL WAVEGUIDE - A surgical probe is disclosed which includes a stiff treatment waveguide extending between a first end and a second end, the first end being adapted for connection to a handpiece, the second end being adapted for insertion through an incision into an area of tissue. The treatment waveguide in configured to receive treatment light from the handpiece at the first end, transmit the light to the second end, and emit the light from the second end into a portion of the tissue proximal the second end. The treatment waveguide is adapted to penetrate through a portion of the area of tissue in response to pressure applied to the handpiece.01-08-2009
20090018531COAXIAL SUCTION SYSTEM FOR LASER LIPOLYSIS - A surgical probe apparatus is disclosed including a handpiece which includes an optical system configured to deliver therapeutic light to provide treatment of an area of tissue; and at least one suction port configured to remove a byproduct of the treatment from the area of tissue in response to an applied vacuum.01-15-2009
20090024023THERMAL SURGICAL MONITORING - An apparatus is disclosed for monitoring a thermal surgical procedure including a thermal camera for monitoring temperature at a plurality of locations within at least a portion of a surgical field undergoing thermal surgical treatment and generating a series of thermal images based on said monitoring, a processor for processing the thermal images, and a display for displaying, in real time, a series of display images indicative of temperature at the plurality of positions.01-22-2009
20090054956MULTIPLE WAVELENGTH LASER WORKSTATION - Lasers capable of lasing at least two wavelengths are provided having a lasing medium which is capable of lasing at a first wavelength and at a second wavelength. An output coupler is positioned along a longitudinal axis at a first end of the lasing medium and a first mirror, movable beam block shutter and second mirror are positioned sequentially along the longitudinal axis of the lasing medium at a second end of the lasing medium. The first mirror is highly reflective at a first wavelength, and the second mirror is highly reflective at a second wavelength while being transparent at the first wavelength. The beam block shutter is movable between a first position along the longitudinal axis of the lasing medium and between the first and second mirrors and a second position away from the longitudinal axis of the lasing medium. Also provided are laser workstations having two lasers driven by a single electronics drive system in which a single energy storage network is connected to a first laser pump chamber operative to excite a first laser medium and connected to a second laser pump chamber operative to excite a second laser medium. In certain embodiments, a switch connects the single energy storage network to a secondary winding of a high voltage trigger transformer, which is itself connected to the laser pump chambers. These high voltage trigger transformer serve to selectively ionize the excitation source in one of the laser pump chambers such that when the switch is closed, energy from the energy storage network will flow through the pump chamber whose excitation source(s) has been previously ionized. In other embodiments, the single energy storage network is connected to the excitation sources via active semiconductor switches that permit the release of portions of energy stored in the single energy storage network to one of the lasers, leaving additional energy to be immediately or rapidly released to the excitation source of the first or another laser. Also provided are methods of treating skin having a skin problem using multiple wavelengths of laser energy.02-26-2009
